Review on Gain Express 1999-1999MV Temperature Gauge 0-14PH by Julius Hunter
PH reader is grossly inaccurate and will not calibrate
I'm still hesitant to keep the tester just for the ORP reader which is easy to set up and accurate. Once it was possible to calibrate correctly. Then I checked my two aquariums. I first ran a chemistry test on both the liquid and the ProScan strip. The large tank has a PH of 6.5 and this reader returned 7.28. My other tank is also 6.5 and the racer gave me 8.1. I tried to recalibrate but failed 3 times so I gave up on the PH part.
