Reference electrode is one of the important components in cathodic protection system. It can be used to measure the potential of the protected structure and can be used as the signal source automatically controlled by the potentiostat.

Cu/CuSO4 reference electrode is widely used in the cathodic protection of buried pipelines, above-ground storage tanks and other metal structures.

The long-acting Cu/CuSO4 reference electrode produced by our company has the characteristics of reasonable structure, reliable function and long service life. According to different market demands and customer requirements, our technical staff has worked hard to develop a variety of reference electrodes of different materials and different uses to meet the diverse market demands. For example, the buried double ceramic long-effect copper sulfate reference electrode which can be buried underground for a long time and has a long service life is used to detect the correct potential signal. Pressure-resistant long-acting copper sulfate reference electrode for cathodic protection of large storage tank floor, Silver/silver chloride reference electrode and high purity zinc reference electrode for cathodic protection of seawater and fresh water measures, insert reference electrode for cathodic protection system of oil storage tank, pressure vessel, power plant condenser inner wall, etc. Our company can also be customized according to customer requirements of different materials, different uses of reference electrodes.
