I recently calibrated my ph probe to find ( I thought) a bad ph probe since it dropped in the am to 7.5 after being calibrated. Ordered a new probe and to my surprise it did the same thing in the am. I’ve recalibrated it 5x and seams like it’s only getting worse.
I’ve tried for interference and stray voltage to no avail. Going to try and get different solutions today. Any thoughts or suggestions are welcomed
