Anyone had trouble with these? I have had mine since Jan. I just changed the battery on it a week ago and my PH (according to the monitor) dropped form 8.2 down to 7.8.
I recalibrated in a couple if times and the readings still run 7.9-8.0
Now I don't trust it. My PH could not have dropped that much in 10 minutes!!
I even took it to my LFS and compared it to his . His showed 8.3 and mine showed 8.0. He then pointed out to me that his had not been calibrated in months.
Should I replace the probe?
