Oxidation-reduction potential.

ORP, or “oxidation-reduction potential” (also called “redox potential”), is a measurement of water’s tendency to act as either a reducing agent (electron donor), or oxidizing agent (electron acceptor). A positive ORP indicates the presence of potential oxidizers, while a negative ORP indicates the presence of potential reducers.
