What is the main function of reference electrode?

2018-01-23

Reference electrode is an important device of measuring metal potentials in the electrolyte, is an important part of the cathodic protection system, not only detect various metal electrode potential as a basis for reference, but also be used as a potentiostat automatic control signal source.
  Cu/saturated CuSO4 reference electrode, high purity zinc reference electrode, silver/silver chloride reference electrode are widely used in cathode protection project, because these electrode potential has very good repeatability, electrode can be used multiple times, structure simple , economical and practical.
  Reference electrode is indispensable important part in cathodic protection system, so the quality of the reference electrode is directly affects the the whole construction and test data of cathodic protection system.
