Web22 aug. 2013 · ORP is measured in millivolts (mV) and on the ORP scale, the presence of an oxidizing agent such as oxygen increases the ORP value, while the presence of a … WebORP stands for oxidation reduction potential. An ORP sensor (or probe) measures the ORP level in the water and displays a corresponding mV reading on the display of the ORP controller. The ORP reading provides a measure of the ability of one molecule to reduce or oxidize another molecule.
