Permanent Cu/CuSO4 Reference Electrode.
Routine potential monitoring is an important part of cathodic protection maintenance program, an accurate, reliable, and consistent reference electrode is crucial for the potential monitoring. We offers high level reference electrode which complies to the highest industry standards, our reference electrodes including Copper/Copper Sulfate, Silver/Silver Chloride, High Purity Zinc, both of them is available in buried and portable type.
Copper sulfate reference electrodes are the most commonly used reference electrodes for measuring the electrical potential of underground structures and structures exposed to a freshwater environment. It is not suitable for use in a chloride electrolyte as the chloride ions will migrate through the porous plug and contaminate the Cu/CuSO4 Reference Electrode. The electrode is composed of a copper rod, immersed in a saturated solution of copper sulfate, contained within a non-conducting cylinder with a porous plug at the bottom. The copper ions in the saturated solution prevent corrosion of the copper rod and stabilize the reference electrode.
Permanent buried Cu/CuSO4 Reference Electrode provides accurate and reliable electrical potential measurements on buried metallic structures.
