Buried Copper/Copper Sulphate Reference Electrode
Reference electrodes are used to measure the polarization potential of cathodic protected structures. They shall be kept in contact with the same electrolyte (soil or water) surrounding the structures, and the voltage that rises between the structure and the lead cable of the electrode, measured with a high-impedance voltmeter, gives an indication of the effectiveness of cathodic protection. Our bagged copper/copper sulfate reference electrode is the most commonly used reference electrode for measuring potentials of buried metallic structures.
