The longer I leave the meter in a solution, it continues to change. I get a change every 3 seconds or so. I have to give it at least 5 minutes to insure a stable-ish reading. I have the Hanna Checker.Less than 6 months old to me., The 4.01 buffer checks out alot quicker than the 7.01. TA testing is a pain with the slow rise of numbers.
Any ideas? Bad battery? Probe???
