Review on π Enhancing Measurement Precision:Accuracy Electrode Calibration Connector Application by Ben Barrington
Don't give money away
I have three ph meters that use this type of probe. I used all three meters to make sure it was a working probe that was accurate. The probe read 2.8 then jumped between 4 and 11 and couldn't decide where to stop and continued its countdown until I disconnected it from each gauge. I have since returned this item
