Hi-
I am new to Apex and the pH Probe has caused multiple issues and calibration. I have calibrated it 3x’s now and have checked it against Hannah pH, my LFS also checked it with his in-store tester and Milwaukee probe and it's been off. I am tired of spending money on calibration solution. It has been a few weeks now and Neptune support has been slow to respond. Has anyone experienced this and been able to fix it or does it need to be replaced?
Thank you,
