Hanna Combo pH Calibration Video

[MrKumpu]

Hey do you guys use storage solution? Is it necessary?

This is very much helpful for the hanna usuers as well, can you help me with an HI 2550-02 calibration for TDS, EC, mV, pH, Salt ets. as maximum.

Once you calibrate it for the first time, how often do you need to recalibrate it there after?

Great video! Ive the grocheck combo meter and Hanna actually states the black combo meter you are using is the most accurate and efficient.

Making the switch!

Thanks again brother!

great job explaining it. You helped me a lot. Hanna makes great meters but their instructions suck.

Do you need to calibrate this when you first get it?

Good video my dude....i read the instructions that came with the effin thing about 50 times , and no where in that little fold out do they say to hold the mode button beyond the point where off is displayed ....i kept letting go as soon as i would see that shit ........... you saved me from launching that meter out the window.....

Thanks, I'm glad someone found the video useful. I refer to the video whenever I calibrate as I can't seem to remember the sequence.
