Copper/Copper Sulphate (Cu/CuSO₄) electrodes are used for potential monitoring in underground pipelines and storage tanks, featuring a porous ceramic sheath and saturated copper sulphate electrolyte. Silver Chloride (Ag/AgCl) electrodes are preferred for seawater applications; with high purity silver and a polyethylene body, they offer a lifetime of over 25 years.
Copper Sulphate
Copper/Copper Sulphate reference electrodes are used for standard potential measurement in cathodically protected underground pipelines and tanks. The porous ceramic tip ensures stable contact with the surrounding ground, thus minimizing drift and noise in measurements. The saturated CuSO₄ electrolyte produces a constant potential for a long period of time, resulting in comparable and reproducible results for periodic checks.
Silver Chloride
Silver/Chloride reference electrodes are designed to provide stable potential in seawater and semi-saline water environments. The high purity silver wire and durable polyethylene housing make the electrode resistant to both mechanical impact and corrosion. Thanks to its long-lasting structure, it is used as a reliable reference point for monitoring piers, ship hulls, platforms and submarine structures.
