Whahaha, "I've pulled the oxygen sensor out because it was giving me continuous alarms"... That's one way of dealing with a hazardous situation. :D
Anyway, good video. Interesting to see all the safety precautions they've taken while designing this device.
Oh... And please don't use a scalpel as a pointing device anymore... My face was like THIS close when you where waving that around. Makes me nervous.

So why was some of the display not working? Was it because some of those diodes had gone open or was there one of those rubber things to connect the LCD.

Excellent, explains very well Ex. An Ex rated Fluke 87V is near $900 versus $300 for the regular 87V. Helps justify all the cost given its all under the hood.

@igsaturation Most of that cost is because it's a low volume product, plus approvals costs - I doubt the the actual build cost of an IS fluke 87 is much more than the normal one.

Mike, out of curiosity, for any given episode, how much of the facts presented that are specific to do the thing being torn down, do you know by heart, and how much do you find during research for that episode? Say something like coating being fluorescent or the specifics of safety standards to take a couple of examples from this episode.

@Gameboygenius Specific stuff is usually from docs I found online, & I say when this is the case. Apart from looking up unfamiliar IC numbers, the rest is generally stuff I already know from experience - e.g. a few years ago I was involved in design of some intrinsically safe products.
