Product Description 1. The reference electrode is an important component in the cathodic protection system. It can be used to measure the potential of the protected structure and also serves as a signal source for automatic control by a constant potential meter. 2. Applications of Buried Long-Lasting Saturated Copper Sulfate Reference Electrode (1) Monitor the cathodic protection status, used for potential measurement in sacrificial anode protection. (2) In an impressed current cathodic protection system, acts as a stable signal source for automatic control, suitable for cathodic protection projects of buried pipelines and underground metallic structures. (3) Can be buried in locations that require monitoring but are inaccessible. For example: at the center of the bottom of large containers; in positions between underground fuel storage and chemical storage tanks that cannot be accessed; under urban road networks, etc. Can be pre-buried during construction and used for a long time. (4) Remote measurement signal source for pipeline cathodic protection.
