 Okay. We'll make a start here. Thank you all for joining us here on a Friday afternoon or rather very early in the morning for one of our presenters today. Welcome back any of those that have joined us previously for our run of webinars for those who have been running this fortnightly for almost two months now, I believe, and these are all recorded for use later by any of you. If you possibly had some colleagues that couldn't attend today that may be interested in these will be able to provide this recording to anyone who requests it, but also will inform you on where to be able to access this at any time after as well. So we're lucky today to have another international speaker join us in order to provide some insight into the great product ranges of Aquaread Mr. Ryan Cox sales director at Aquaread. My name is Kyle McLaren. I'm the sales manager here at Hydra Terra. And we also have Michelle our general manager here at Hydra Terra overseeing things and making sure everything's running smoothly. So just quickly a bit of housekeeping at any time, please feel free to type any questions you may have in the Q&A box situated in the taskbar there. What I'll do is at the end, once we're done presenting the content I'll read out as many of these questions as time will allow us and myself and Ryan will work through answering as many live as we can. If we can't get through the wall, of course, I will endeavor to make sure that I get them answered personally. So as always, we see these webinars as a really effective and efficient way of generating awareness across Australia on the various technologies that we've seen and perhaps you guys may not be aware of yet. We always want to strive to build as much training as we can into the work that we do. This is probably the most important thing when looking to have the ability to adopt technologies in the future. And lastly, we identify what is important for you and your industry needs by having these discussions and generating awareness. We always look forward to seeing, you know, some of the weird and wonderful ways you guys need to monitor and I personally really enjoy that. So the program today as we have is that the main body of the webinar will be handed over to Aquaread's very own Ryan Cox who will talk a bit about the range of products as well as some examples of applications which these have been utilized in previously. I'll then just mention the units we also have available within our rental fleet as well of a couple of quick examples, perhaps of some applications from existing clients of ours as well with the Aquaread range. We'll then finish up as I said earlier with a bit of a Q&A with Ryan and myself. So, again, I'll probably let Ryan tell you a bit more in detail who Aquaread are if you don't already know, but the British design and manufactured water quality instruments, sort of a vast global presence in over 50 countries. But, you know, we've now been established Hydraterra as an exclusive distributor for nearly a year now and already in that time we've identified that, you know, Aquaread is a great suite of products and we're really excited to represent them as we've seen a huge number of interest here in ours and as well as NZ. So I think that's enough for me for the minute. So I might take this time now to hand over to Ryan if I can please. Sure. Let me just share my screen. Is everything okay with Ryan? Yeah, good. I'm just getting the, it's because I'm going to use two screens. Do you need me to stop sharing or? Ah, that should. Yeah. Can you, so you can see the presentation now? Yes. Good. Okay. Sorry about that. It's probably because, yeah, I've never done a, I've always sort of shared my screen. I've never had to sort of share it over the top. Yeah. Sorry about that. So anyway, so yeah, thanks, Kyle. Um, what I want to talk about here is, is, um, one of our, one of our most popular products. And then I'm going to show, um, some data, um, from telemetry. And then I'm going to touch on a, a case study, um, which we can send that round afterwards. So we have a case study sort of prepared if that's okay. So, and then obviously as Kyle said, we can take questions, um, at the end. So that comes from this webinar or the outcomes from my section. So I'm going to, um, talk to you about the AP 2000. Um, and I'm going to give you, um, just a brief overview. I'm not going to, I'm going to do my best to try not to, you know, to sell it to you. Um, but this really is just giving you a technical, um, a technical overview really of what the, um, what the AP 2000 does. And then I'm going to show you some, some data, um, that's coming back, um, from one of these probes. And then I'll talk to you about a case study that, um, that we did. Um, the case study I'm going to talk to you about was from a while ago. Um, but these probes just hold, um, all over the world. And we have, we do have newer ones, but the one I've got is, um, it's quite good. Okay. So just a brief introduction to, to Aquaread. So Aquaread has been, been around for, um, since 2008. Um, we've been around for, you know, 11 years now. Um, we've been in Australia actually since, since not long after the company formed. Um, we were present there, represented by somebody else. Um, and then recently we've, we've moved to Hydra Terra, an exclusive distributor, um, in Australia and New Zealand, which was a great move. So we fit well with, with Hydra Terra and their best place to support it. Um, as we continue to grow. So everything, all of our products are designed and manufactured, um, in England. So, and that includes all of the sensors. So it's quite a verity really for a company to, to produce and to, to design everything themselves. Normally companies in our industry would, um, you know, um, produce a probe, but then they would buy the sensors from the company or use others designs. We don't do that. So our designs are obviously industry standards. So the probes that you, you get from us, you know, you would recognize. Recognize how the sensors work and so on, but it's, it's all of our own design. The benefit of that, obviously I'll talk about, um, a few slides time. It's all of our staff. So we have around 25 staff. Um, something like that. Um, all of the original founding members of Acra Reader still there. So we have scientists at the company, technical team, product designers. All of that said, and the whole set of capability is read. Are you flicking through the presentation? Yeah, I'm talking about this, this particular slide. So you should, you should be seeing the introduction to Acra Reads slide at the moment. Okay. We're not seeing it. We're just seeing the, uh, the front auditor webinar page. Sorry. Number one. Right. Can you stop sharing your screen please? Uh, that's better. You should see it now. You got it? Yes. Oh, good. Ryan, thank you. Okay. Good. Yeah. No worries. So as, as I was saying, um, so this is the slide I was talking about. So I wasn't talking like, you know, to sorry about that. I wasn't intending on talking to a, uh, an open presentation. But, uh, this is the, this, these are the slides I wanted to talk at. So, um, so our products. So we offer a full range of products. So we have the, um, single parameter product right through to the multi parameter product. Six senses. Viper. We do a sound, um, or range of songs for permanent deployment. And then we produce a range of levels. And again, all of those are made in house. We have distributors in over 90 countries. And I should say 50 countries all over the world. And that continues to grow. So, um, and then everything we do is produced to ISO, um, standard. So this is the, um, particular product I wanted to, to talk about today. So it's the AP 2000 relevance to this is it's the most popular product we do. Um, it's the best at ground water monitoring. Um, it's because it's so portable. So, and usually customers will do sort of ground water applications with this, with a flow cell, they'll do chemistry profiling, going down a borehole, um, the spot measurements, the surface water depth profiling with the level sensor. And then they'll do a short, short to medium term deployment. So this probe really is designed to be, um, carried around and taken from, from place to place. But it can be put on telemetry as well. And I'll show you some data, um, from, from this program, what it looks like in a few minutes. So the technical advantages of this probe is it's optical. It's dissolve oxygen sensor, which uses optical technology. So that's not new news. Um, you know, I'm not telling you that because, you know, I want you to think, oh, great. Yeah. We've, we've designed, you know, optical dissolved oxygen sensors. They've been around for some time. The optical sensor is our own design, um, for Dio. And what we've done is we've combined, um, dissolved oxygen and EC. The reason we've done that is it saves space in the instrument. The instrument is actually only 42 millimeters diameter, very thin. So it will go down to 50 mil, um, standpipe or borehole. So that's a real advantage. There aren't many, um, probes or there aren't any rather probes that measure 13 parameters, um, in one probe that's a 42 mil body. Normally then they're four inches plus, um, because of the sensor size. So we use, um, because we're a relatively new company, the technology and the design is, you know, it's right up to date. So we're using sort of the latest design methods, um, and, you know, electronics design so we can keep things, um, to a smaller scale. So in addition, you can add in two additional sensors to the standard sensors that come with this probe. So this probe will measure, um, pH, dissolved oxygen, temperature, and EC. And then you can add in, um, our selector sensor so you can have things like nitrates in there. And then you can add an optical sensor. Um, because the refined oil will be unhappy and stuff. And all of those sensors, you know, we produce in-house. So when technical, um, concerns or questions come up, not problems, but, you know, technical concerns, you know, often come up with sensors. So when you're working on a specific project, for example, recently I had a customer where they were, um, they were looking at, um, refined oils. And they reported back to us that the, um, that the sensor wasn't giving, um, the expected results back. So we downloaded the data from their, from their probe, or they sent the data to us. And the sensor was fitted to one of these probes. And what the customer was doing is they were using the meter, which you can use the case, um, here. And they were just recording the data. They were leaving the probe for about, um, for about five days. So then this was in the IK, um, like a more of a process application, really. Um, but it's obviously still, um, you know, groundwater water-related. And they're reporting that the, the hydrocarbon sensor wasn't actually recording any hydrocarbon. Um, so what we did is we downloaded their data. And with our sensor, you can actually calibrate to your relevant chemistry. So, um, rather than using like a, um, the family insult, which is what we use, we invited the customer to actually calibrate the probe in their own chemistry. So, and what that basically meant then is the probe was looking at, looking for the right chemistry. So when it was, um, um, for resting, it was then looking at the right chemistry and recording the right chemistry and then actually recording some data. So we, you know, in terms of our customer support, we were able to analyze that data and then work, um, to a scientific level, um, with that customer and their team. So that goes back to the, the previous slide, which talks about, you know, capability. So we don't necessarily just, you know, produce the product and then leave customers to it. We have the backup as well. And there are other examples as well, you know, refined oil, um, is one example. Of course, you know, with all, all sensors, all additional sensors that you can add in, there are all its questions. You know, there are always, um, things that you guys want to know, um, in terms of, you know, well, I think I should be seeing this, seeing this, you know, what's the reason for that, you know, so we can go through all of that and no hydroteric and customer support. Well, so we use marine grade aluminium, um, construction for the probes, the pro, all of the probes are anodized. So they are, um, well protected from corrosion. And then the probes are versatile. So they can be used with the handheld meter, um, which is in the case here. They can use, used on telemetry, um, or they can be used with a logger that we produce, the, uh, the aqua logger. And then they can be, um, used in form of a sound. You can actually have batteries inside the probe and have memory inside the probe and you can deploy the whole thing, um, into the water and that gives you up to a nine month battery life. Okay. So that's the AP, uh, as an overview, that's the AP 2000. So these are some of the key things that it, that it can do. Um, groundwater is, is its main, um, success. That's where customers enjoy using it the most. So they enjoy using it just to wrap up for the, for the amount of parameters that it can measure. The fact that they can, um, exchange, um, the sensors. So you can change the sensors yourself. So you can add in additional sensors. You don't need to send it back to the factory. Um, for that exchange the cables through versatile unit. One of the other things that the, the AP 2000 has is, um, the optical dissolved oxygen sensor, which is why we actually did a presentation on this and hydroterror have already, um, shared that. I think haven't you, Kyle? The, did you share that Kyle? Yeah, that's right. Yeah. Okay. So I won't go into too much detail about the, the DO sensor today. And everyone, because they've already, already seen it. Um, considering it was my voice as well, which, yeah, probably painful at times. Yeah. Well, it wasn't too bad actually. It was slightly, it was slightly, yeah, slightly later in the day that, so I was a bit more awake, but, so the, so the AP 2000 uses the, the optical DO sensor. So with, with these sensors, there's no flow of water required. Our sensor holds its calibration for up to six months. So that's the, the zero point, um, calibration. Um, and then you don't need to change the, the end cap as often. So in, in the previous presentation, I talked about that in detail, but basically here, this is the, um, on the bottom left, you can see the DO sensor and you can see the blue LEDs and the red LED. And then in the center, there's a photo detector. So that's, um, just light base and basic form. It's, it's, um, dynamic luminescence quenching technology. So in, in basic terms, we vary the brightness of these LEDs over the life cycle, the probe with the same end cap fitted to the dissolved oxygen sensor. So when the probe is brand new, these LEDs are actually, um, very dim because the cap, the end cap, um, is, um, is completely black, basically. So no lights, um, can get to it. And over time, the, the end of the end cap, which I'll show you in a second, um, basically becomes more, more opaque and allows the lighting to be out. So what we do here is raise the brightness of those LEDs through calibration. So each time you calibrate the probe, um, be it either a zero point for dissolved oxygen or the 100% saturation point, the meter will check, um, the cap and it will increase the brightness of those LEDs. So in doing that, um, the dissolved or the membrane cap can last up to 10 years. So whereas with other companies, you can change the cap every year. Um, so that's a, that's a key feature. It's also very fast. So it takes milliseconds, um, to take a stable reading. Um, it re, reaches T90, which is the, um, maximum reading it will be, or maximum reading it will give, um, in about 20 seconds. There's a very quick, very stable sensor. So as opposed to, um, a galvanic sensor, which we, we do make, or we do have on, on the AP 700 and 800. So those are products that, um, at the beginning of the range will cost effective options. Um, but the galvanic sensor is a little bit slower, um, requires a lot more maintenance. And, um, it is a stable, uh, it's nearly as fast, but it does require monthly cap changes and monthly maintenance. So really the AP 2000, um, provided there's some basic points, um, points met each time you use it, requires very little maintenance really. The DO sensor doesn't need any special storage. So it can just be left dry. And each time you sort of take it out of the box, um, it's going to be, um, going to be good to go. And then on the bottom right, you've just got the, the, the various, um, specs really, um, obviously things you'd expect, IP68. Well, yes, you would expect to watch Probe to be, to be waterproof. Um, and then we have a maximum, um, deployment depth of 100 meters. So because this probe is just designed for, you know, spot checks and profile. Okay. So these are these, uh, the things we produce, um, we produce these for all of our probes. So, and as I said on the, on the first slide, these are our own design. We include, um, the standard parameters as standard. Are you at no extra cost or, or or no sort of user configuration? Um, these just come with the probes. Um, the AP 2000, no exception. So you get the optical DO sensor, PHR, PEC and so on. Um, and then you have the option of taking depth. The additional sensors, which I mentioned, or here's the list, um, on the screen now. So you can choose any of our ISE, ISE sensor and any of our optical sensors, and you can fit, um, any one of those to the AP 2000. Um, the specs are available, um, in the literature which Hydratera provides. So we generally have quite a wide range of detection with our sensor versus, um, our competitors. So our ISE sensors, um, for example, have a very wide range. Basically that means that the sensor is more versatile in the field. Um, if it's calibrated correctly, um, you know, they're very accurate. Um, we did a lab analysis, for example, with, with ammonium, or ammonia, rather. Um, and we basically did, um, we had a, um, known sample. So we knew exactly what the levels were. It had been tested by a piece of equipment in our laboratory. And then we used an AP 2000, which I calibrated. Um, and then our scientific director had the known sample. And we were actually within 1% of the reading that had been verified by a you know, um, piece of scientific equipment that, you know, has potentially far greater accuracy than, you know, than a ruggedized field probe. And it was an AP 2000. So you can get great accuracy with our ISE sensors. Um, it all really just comes down to the calibration. Um, making the calibration solutions can be tricky. Um, but, you know, if I can do it, um, you know, generally anybody can do it. So it's not a particularly, um, difficult process in calibrating these sensors. I think it's just the, um, making up of the solutions is the most important thing. So, yeah. So the best, you know, if you make the solutions up using sort of plastic where that's generally, um, the best method. So if they're made up correctly, um, at the exact correct level, you know, give or take a little bit, then ISE sensors will be most accurate. So, and I'm mentioning this at this point because these are just sort of relevant bits in case any, any of you have already had an ISE sensor from us or a thinking of using it. So they're not, um, you know, they're not problematic. They work very well. Um, they last, um, six months and then need to be replaced. Um, the same as, um, any other ISE sensor. It's just down to the calibration, but we have a quite a good guide in our, in our, in our manuals, which, um, is taught in the process, but the takeaway points from what I was just saying is if anyone has or will have an ISE sensor, make sure you have plastic, um, uh, serological pets or plastic measuring there as opposed to glass. Um, because glass, you get basically meniscus and it sort of adds in um, more calibration solution than you would have measured out. So we're just, you know, follow that process and use plastic where that's the, that's the most simple advice for those. So the optical sensors. So we have a um, turbidity sensor, chlorophyll, glugrin algae sensors, rhodamine, porousine, refined oil and seed, um, eftom. So the usual suspect really for optical sensors. We just use, um, either light based, um, turbidity or they'll use fluorescence um, for the other parameters. And basically they're just LEDs that fluoresce a certain wavelength which happens to excite those listed chemistries. So, very, you know, very simple sensor, um, very powerful sensor, um, and they're calibrated quite much more easily than, you know, any sort of wet chemistry pro. You just put, you just, you just put them in a um, a simple reagent and you do a zero point and a higher point for example. So for turbidity you would do zero NTU which is de-mineralized water. Um, you know, so you can go and buy that from the local store. Um, just a bottle of, you know, Buxton's water and then you do a thousand NTU points and that process takes about, you know, less than a minute. So it's very simple. Um, and then the other sensors, you know, we do provide the, uh, the reactions for those. So, and these specs again, you know, we have a wider range um, you know, we have quite a, um, we have more optical sensors as well than the vacuum testers. So have a look through the literature after a, afterwards and, you know, look at the specs and so on. And as I said before, you can add, um, one of each of these sensors to the AP2000 um, in addition to standard parameters, which it comes with a standard. Okay. This is what the AP2000 looked like. Um, it's 42 mil in diameter, as I said. So this is a fully loaded AP2000. So this is what it would look like populated with um, loads of sensors. So you've got the DOEC and temperature sensor here. So that's the optical DOE sensor cap I was talking about earlier. So you can see there when it's brand new, it's nice and fresh. And then we've got the PH sensor here. Our PH sensor, we actually use a Combi electrode. So it comes with ORP, which you can see on the pin here. And it's a um, ceramic junction um, gel filled electrode. It's not refillable. We don't do a refillable PH sensor. So the idea of this is it's very stable and you replace them every 12 months. And this is something you can do because you can see the threads here. So the idea with a replaceable PH sensor is some customers say, well, why can't you just make it refillable? Sure. You know, we absolutely, we could make a refillable sensor and fit them into our probes. It's a refillable sensor. It's generally, unless you take them into a lab and make sure they are absolutely clean and refill correctly, you know, with fresh, clean solution. And then calibrate it fully. You know, there's a lot of margin for error. You know, it can happen there. You know, most customers will do it properly. Most of our customers want something that they can do and just take into the field and just use it to feel ready without having to sort of mess around with, you know, refilling PH sensors. Some competitors, for example in Situ, they have a very nice refillable PH reference. So, you know, they don't use a gel-filled sensor like ours. You can keep refilling it. The advantage of that is you don't have to keep exchanging the PH sensor. But, you know, in response to that, our PH sensor is actually generally low cost. So, it's not an expensive thing to replace on a yearly basis and it's very accurate as well. You know, but the added advantage to that is you can just buy the PH sensor from HydroTera, screw it into the probe, do a calibration and the whole thing takes you about five minutes. So, there are advantages for PH sensors, you know, all sorts of different PH sensors. Usually, with these probes, you have one PH sensor designed and it's sort of designed to fit all applications. Obviously, PH is a massive thing and there are loads of different types of PH sensor you can buy. We do do a couple of different options. So, this PH sensor you see here is standard. That's that standard offering. We do one for low EC environments. So, anything below or below 150 microseconds and this sensor will start to struggle. It's rare that you would, you know, be measuring in, you know, that sort of water generally. So, we do a low EC version and then we do a double junction Teflon junction version and that is actually better for harsher chemistry. So, if you're looking at sort of leachate, you're looking at anything like that. We have a double junction sensor. So, we do have some options. So, the idea with a double junction sensor is it is less prone to saturation than a single junction sensor. And the Teflon junction is just more hardy basically for the chemistry. So, we have a couple of options. It is rare that people take those, but in Singapore, for example, they do take the double junction sensor as standard just by virtue of the fact of what they're doing. So, they're actually in an saltier environment there. So, higher EC and they're actually using this particular model in fish farms. So, which obviously presents its own challenges. So, they don't use any unselected sensors because of the high salt content. But we do have sort of different configuration for those particular types of applications. So, just to wrap this slide up. So, you have the DOEC sensor here on the right hand side. That's where the pH sensor goes. And then you have a depth sensor in the middle. Temperatures on the DOEC sensor. And then you have a port for the optical sensor, which is the large port. And then you have a port for the ISE sensor. These are sensors you can replace. You can add those in. So, you don't need to buy all of your sensors all at once. It comes with the standard parameters which are on the left here. And then you can add any one of these in a later stage. So, it's configurable at any time. Okay. I haven't got too much left now and then I can I'll stop talking, I promise. So, ways of communicating with the probe just quickly. So, we have a GPS aquameter. I'll go into a bit more detail on that on the next slide. That's our standard way of communicating that probe. So, every package comes with one of those meters. The meter does everything. So, it allows you to calibrate the probe, which is a simple push button process. So, you don't have to input things like on other probes things like atmospheric pressure. You don't have to adjust the pH scale. Anything like that. You get the reagents. You make the reagents up. You open the reagents. You clean the probe. You put the probe into the reagents and then you press the button. The meter then does it automatically for you. So, the meter knows what the solution should read. What the probe should read. And then it will calibrate. Calibration is stored in the probe, not the meter. So, you can use any meters, any aqua-read meter on that probe. So, you don't have to use the same meter. All the information is stored inside the probe body. So, we do a logger, which is called the aqua logger. So, if you want to leave the probes out in the field for a prolonged period of time, over a week or if it's going to rain or such like, use the aqua logger because it's waterproof. And the aqua logger will sit on the surface and report up to 32,000 steps a day to give you six months battery life. If you want to put the probes onto telemetry, you use the black box, which is this device here. It is actually very small. It looks massive on the picture, but it is very small. It's just a little bit bigger than a credit card. And that basically converts our probes language into SDI-12 or Modbus. So, our probes don't output SDI-12 or Modbus standard. You do have to use a converter. Some people don't like that. But the thing I would say to that is the black box ensures that the data you receive to your telemetry, the telemetry minute data is the same as if it was you were using the meter up here. There are no differences. So, this black box will do all of the temperature corrections for your PH, ISC, all of the sensors. It will do the atmospheric pressure compensation for the required sensors including depth because we don't use vented cable. We have a pressure sensor in the meter in the aqua logger or in the black box. And then it will cancel out any noise as well. So, telemetry devices can be noisy when you're on site unless you have nicely perfectly terminated connections. There can be noise, noise interference and such like this device will cancel out all of that. So, PH sensors, for example, are prone to noise and interference from obviously electrical current connections and so on. The black box will cancel and also protect the probe. So, if anything happens to the logger or the telemetry device which is rare, but you know if it sends too much power down the line you know you try and send too much power it's going to blow the fuse in the black box which you can replace. Obviously, if you have it connected to the probe directly it will blow the probe up and it's a case of $5,000 from this probe where you spend a couple of hundred dollars placing a black box. Full information on that is available but I'm going to show you some data in a few seconds on that. So, just wrapping up now only a few left. So, this is the aqua meter so this is our main communication offering with all of our probes. So, those are some of the points there things that it comes with. So, you basically use this so you can scroll through the screens but use it to view the data you can record the data into the probe's memory using these keys here pretty much like a calculator it has the atmospheric pressure arrow sensor built in so it will do the same compensations and so on so the data you see here is ready to use there's no external offset corrections needed this is the prep data it's IP67 so you can submerge it down to a meter but generally it's you know it's happy to be rained on and so on so, that's the that's the aqua meter you can clock the data onto Google for maps so it has GPS built in so for example here this is a river in the UK from memory yeah sandwich, yeah that would have been embarrassing if I was talking about a river in America or something I'm sure I recognize this picture somewhere but this is near to our office so what happened here is a customer or a customer from an environmental consultant basically just a chemistry profiling went up and down the river and then they recorded at different points so what the meter has a very good GPS chip on it so it's very accurate full spec is in the manual hopefully no one asks me exactly what GPS spec it is because I can't remember but I'll figure out the manual if you do ask so what it's done here is it's plotted to different readings as they walk down the riverbank and it's recorded the chemistry naturally at each point then they've plotted it to this map so the advantage of this is you can plot chemistry and you can see the change as you go along so it gives you know more string to the bone in terms of data lots of customers do this so you don't have the ability on the meter to add in a text based site ID or OID so there isn't actually the option to enter text in the meter but the GPS is good enough that you can actually discern between different bore holes or different locations in a river so this is like a a good feature customers use it a lot there's one particular customer that uses a lot in the UK so they switched over from a YSI handheld which allowed you to enter text points so they were kind of like well you know we want to enter a text point you can in the software which I'll show you in a second after but you know they've just been using the GPS and it's good enough so okay and then finally this is the software so you can download this software for free this allows you to download the data from our Aquameter which I've shown you and then you can enter site IDs and this is where you export the Google file as well this software is free to download it's in a number of different languages but you can export the Google file here and then you can upload that to Google Earth or Maps so I'm going to stop talking now I think I've gone on a fair amount hopefully that was a bit more technical overview of what our probes can do we do have other webinars which hopefully we will do again with HydroTERA which are much more technical and discussing you know a sensor in detail this webinar is just an introduction to the AP2000 but it's designed to hopefully speak your language a bit and sort of tell you how it actually works for you hopefully I've managed to do that and then I guess I'll hand back over to Carl we'll do questions I suppose if that's okay yeah sure yeah stop sharing mate good to have it back so you can see that yes oh good Carl thank you thanks Ryan that was a good insight into the AP2000 and just a few of the features and that sort of thing sort of times getting away from us a bit there so I think we'll we'll look to explore a bit more into the range of the aquareed stuff there's a continuous monitoring in the 5000, 7000 with a lot more parameters and all that sort of thing is very good also so I guess I'll quickly touch on a couple of examples a little closer to home here just to give you an indication of some of the ways which which aquareeds being utilized so far for us in Oz firstly Minja Gold Pajingo Mine up in Queensland near Charter's Towers you know three AP2000 handheld units which have been utilized for over 10 years which is only recently two of them have needed a couple of new meters so really robust sort of meter there especially up on the on the harshest sort of sites like the Gold Mine up there so sort of testifies I suppose to the robustness of them 20 to 35 groundwater bores per month with these units as well as the surface water and wastewater discharge area so really high utilization of the equipment here and the statements from the Worm Area and Gemma up in Minja Gold there's ease of navigation and calibration with these much to what Ryan was talking about it's very easy to hold the calibration and extremely easy to navigate the meter as well which was testimony from these guys also extremely easy to clean the probe with its components as it can be easily unscrewed and screwed up thoroughly again with those interchangeable sensors that you can it's very much customizable and very much to your own so and finally there the Maloon Institute which is also a really exciting prospect for us and really exciting prospect to be able to showcase I guess the full aqua read capabilities and the range so just recently the Maloon Institute in New South Wales will be looking at an extensive sort of floodplain monitoring strategy which will utilize aqua read probes in the AP-7000 which is essentially AP-2000 on steroids with the big wiper as well for the more sort of long-term continuous data and a lot more parameters as well up to telemetry through the use of the black box which Ryan spoke about and will be hosted by the data hosting platform data stream two times AP-2000 and more than 50 locations which will utilize the level line conductivity, temperature and depth gauge sensors so in sort of aqua read also does a titanium based level line in both level and temperature and conductivity so it's a project in which they'll be capturing the Maloon Institute's key catchment health indicators in order to develop sort of guidelines for sustainable but profitable farming so that's an exciting prospect and I'm sure positive that a formal case study will be coming out of that and if you want any more details on any of those please feel free to contact us and our information will be at the end of this PowerPoint presentation so just finally what I'll say is that the amount, the equipment that we have in our rental fleet here at Harjatera so if you're interested at all from the things that we've spoken about today that Ryan has spoken about or myself that might interest you in perhaps looking at the aqua read equipment but might not be best poised anywhere we do have a large rental fleet that you can utilize which has the aqua read stuff here so the AP light which is just one sensor of time the AP 700 more of a economically friendly handheld device the AP 2000 which was talked about extensively by Ryan the AP 5000 and the AP 7000 so I guess when we go up to the AP and we go into the higher 2000, 5000 that's essentially some extra features but also more parameters capable for that monitoring I guess the AP 7000 sort of the cornerstone you'd say Ryan for the long term continuous monitoring with that external wiper as well so we'll endeavour to talk more about those in another upcoming webinar we might sort of target to a continuous water quality monitoring webinar or something like that but in the light of that I think we'll just look to take any questions that you guys might have had so thank you for your time there I noticed that Giuseppe had one question Ryan which is probably best poised to answer is the ratings calculated for the iron selective electrodes they calculated there's a rate using an algorithm or is it a real value it's a real yeah it's a real value so yeah there's no algorithm in there so obviously there is some maths in there an ISE sensor is just an electronic but a bit more advanced than a multimeter but you know it's just taking an electrical current basically that's how it works but yeah it is a real reading the maths comes in obviously converting that reading then to you know two milligrams a litre or a ppm but no it is a genuine reading there's no sort of algorithm or rate that's just the correct answer and that's answered what because it was asking but I think it was excellent if there was any other questions at all I'll just for a couple of seconds here in case anyone else wanted to ask something but in the essence of time I suppose we'll leave it there and I will I'll be sure to answer any other questions that you guys may have in terms of in terms of costings and everything as well be sure make sure to just contact me my email addresses there and I'll be sure to provide those to you for anything that you may want to look at so thanks very much for your time here today everybody and especially thank you big thanks to yourself Ryan for coming and talking I know it's very early where you are this morning so we appreciate it yeah it's fine as heaven though in the mornings there you go thanks very much so thank you all and we'll leave it there
