Product Introduction 1. Reference electrodes are an important component of cathodic protection systems. They can be used to measure the potential of the protected structure and also serve as a signal source for automatic control by a constant potential meter. 2. Applications of Submerged Long-Lasting Saturated Copper Sulfate Reference Electrodes (1) Accurately monitor cathodic protection status, used for potential measurement in sacrificial anode protection. (2) As a stable signal source for automatic control in impressed current cathodic protection systems, suitable for cathodic protection projects of buried pipelines and underground metal structures. (3) Can be buried in locations that require monitoring but are inaccessible. Such as: the center of large container bottoms; areas between underground fuel storage facilities and chemical tanks that cannot be approached; underground utility networks beneath city roads, etc. They can be pre-buried during construction and used for a long time. (4) Remote measurement signal source for pipeline cathodic protection.
