Product Introduction 1. Reference Electrode Introduction 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 of a constant potential meter. 2. Applications of Buried Long-lasting Saturated Copper Sulfate Reference Electrode (1) Accurately monitor the cathodic protection state, used for potential measurement in sacrificial anode protection. (2) In the impressed current cathodic protection system, acts as a stable signal source for automatic control, suitable for cathodic protection projects for buried pipelines and underground metallic structures. (3) Can be buried in locations that need monitoring but are inaccessible. For example: the central bottom position of large containers; positions between underground fuel depots and chemical storage tanks that cannot be approached; urban underground pipeline networks, etc. It can be pre-buried during the construction period and used for a long time. (4) Remote measurement signal source for pipeline cathodic protection. 3.
