well i finally made the piece of crap get on the 7.01 calibration mode, and switched from 7.01 solution to 4.01 solution. The reason why mines a pos is it takes forever to stabalize, it will keep going up or down and sometimes it gives false readings. I've seen it show 7.5 on 6.5 water and after putting it in the 7.0 solution, and getting a steady 6.95-7.2 out of it, it will show 6.5 in the water, right where my test strips are showing. I think its fairly acurate but it needs to stay in the 7.0 solution before testing water.
TurboALLWD Reviewed by TurboALLWD 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
