ORP Probe- mV Measurement (±1999mV)
Taking ORP (Oxidation Reduction Potential, mV) measurements, the range
is -1999mV to +1999mV. Please remove the electrode soak bottle before
measurement. To take the readings
1. Rinse the probe with de-ionized or distilled water before use to remove
any impurities adhering to the probe.
