Note that ORP measures the 'net' redox potential and, in the case of an ion-specific potential measurement such as Es, if the aeration or collector addition rate is changed, then the ORP will change and the Es value will need to be checked (with a laboratory probe). Many things contribute to ORP: oxidants, reductants, temperature and of course pH.

Understanding ORP: Oxidation Reduction Potential

Dec 02, 2016  Oxidation Reduction Potential (ORP) is a measurement of sanitizer effectiveness in water. ORP is an electronic measurement–in millivolts (mV)–of the ability of a chemical substance to oxidize or reduce another chemical substance. Both oxidation and reduction are chemical processes involving the transfer of electrons between molecules ...

Basics of ORP Yokogawa America

ORP (Oxidation-Reduction Potential) is the measurement, in millivolts, of a solution's capacity for electron transfer (oxidation or reduction). ORP measurement may also be called REDOX for REDuction OXidation. The name reflects that fact that within a chemical reaction reduction and oxidation are complementary; one cannot occur without the other.
