I use a Hanna Also, thought because i see them around alot they were good meters, found out the hard way thats not the caase. What do you reccomend that won't break the bank?
socialistpete Reviewed by socialistpete 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
