    Abstract: An apparatus and method for measuring and monitoring the corrosion potential of engineering alloys used in aqueous systems is disclosed and claimed. The method is applicable for a variety of alloys including, but not limited to, copper-based, iron-based, nickel-based, other metallic-based alloys, and their combinations. The corrosion potential is typically determined by measuring a voltage between a specific material in the described oxidation-reduction potential measuring device and a reference electrode. Corrosion potentials for specific materials of construction may be used for diagnostic or control purposes.

    Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.
