ORP (Redox) - What is Reduction-Oxidation Potential?

Oxidation / Reduction Potential indicates whether the sample is in a oxidation or reduction state. The ORP of a solution is measured in mV using a redox meter. The more positive the potential, the greater the chemical species' affinity for electrons and tendency to be reduced. ORP is an indicator water quality parameter used for process control of chemical reactions; for anoxic or aerobic digestion.
