The potentiostat is a key device for supplying DC current to the surface of the protected metal structure in the impressed current cathodic protection anticorrosion project. The potentiostat itself is a branch under a rectifier with constant potential and constant current function. Constant potential refers to the reference electrode feedback as a constant standard to control the output of the finisher.
