Review on π Marine ORP Monitor by American by Katie Jackson
This counter was a waste of money.
Unfortunately I kept the meter for several weeks before opening it and using it on my sewage treatment plant. It seemed to work fine for a week. Then it stopped reading accurately so I tried the calibration. This didn't work either. I turned the calibration screw fully in either direction and still couldn't change the reading depending on what environment the probe was in.
