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.
YUXI 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 (CSE) are the most commonly used reference electrode for measuring potentials of underground structures and also for those exposed to fresh water. It is not suitable for use in a chloride electrolyte as the chloride ions will migrate through the porous plug and contaminate the CSE. The electrode is composed of a copper rod, immersed in a saturated solution of copper sulfate, held in 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 CSE provide accurate and reliable potential measurements on buried metallic structures.
