Ran through calibration on my brand new PH probe a few times today and cannot get it to read correctly.
Value 1 = 7.00
Value 2 = 9.00
Using GHL pH calibration fluid.
It goes through the calibration without issue, but after complete, with the probe still in the 9.0 solution, it is reading 7.00 PH.
I put the probe in my tank and it's at 5.8. in the 7.0 solution it's reading 5.
Doesn't matter how many times I recalibrate or whether I do it on the P4 or GHL Connect or the Control Center.
Is it a bad probe? Bad solution (brand new from BRS)?
