just be gentle with it. watch the glass probe and try not to knock it into anything,don't throw it around the room and you should be fine. but if you notice not a single person has sed any sort of realistic response or first hand response on what the issues are with it.
disrupt86 Reviewed by disrupt86 on . Anyone have instructions for Hannah Ph meter? So i took my newly purchased, used digital ph/ppm meter up to the local hydro shop so i could get it calibrated. Well the guy didn't know shit about hannah meters and after messing with it for a bit, he gave up. I did buy 7.0, 4.0 and ppm calibration solution. My question is: Why does it say while calibrating ph, "use 6.86"? it use to say use 7.01. then it goes to use 4.01. So I do all of that, using 7.0 where it says 6.86. Still reads funny. maybe i need a new electrode? Any info on the Rating: 5
