ORP Meas uremen t
ORP stands for Oxidation-Reduction Potential, measured in mV. It’s also called redox. ORP is a measure of the
cleanliness of water & its ability to break down contaminants. A separate ORP probe (ORP60-DA) needs to be installed
to be able to measure ORP.
Power on the PC60-Z tester, unscrew the original probe, and install the ORP60-DA probe, then the tester will
automatically switch to ORP measurement mode (Refer to Section 14 for how to replace a probe).
Rinse the probe in distilled water and dry it. Dip the probe in sample solution, shake for a few seconds, and allow it to
stand still. Get the ORP readings after appears and stays on screen.
