Abstract
A device for measuring oxidation-reduction potential at operating temperature and pressure in hot water systems is disclosed and claimed. The device includes a flow-through cell, an oxidation-reduction potential probe, a temperature detector, and an external pressure-balanced reference electrode assembly. Each component of the device works in conjunction with the other components and each has electrical connections that transmit signals to a controller. The controller calculates and determines adjustments to feedwater chemistry for the hot water system.
