Cu/CuSO₄ Permanent Reference Electrode for Soil and Buried Structure CP Monitoring
Custom Cu/CuSO₄ permanent reference electrodes for buried pipeline cathodic protection monitoring, underground tanks, tank bottom CP systems, buried steel structures, utility pipelines, test stations, and long-term soil potential measurement.
Permanent Soil Potential Monitoring for Pipelines, Tanks and Buried Steel
Cu/CuSO₄ permanent reference electrodes are commonly used for potential monitoring in soil and buried structure cathodic protection systems. They provide a reference point for measuring the potential of buried pipelines, underground tanks, tank bottoms, and other buried steel structures.
In soil CP projects, reference electrode selection should be reviewed according to soil resistivity, soil moisture, installation depth, cable route, test station location, backfill or surrounding material, monitoring system, and project documentation requirements.

What Is a Cu/CuSO₄ Permanent Reference Electrode?
A Cu/CuSO₄ permanent reference electrode provides a stable reference point for electrochemical potential measurement in soil and buried structure cathodic protection monitoring systems. It helps engineers measure the potential of a buried steel structure relative to a reference electrode.
In soil and buried CP systems, Cu/CuSO₄ reference electrodes may be reviewed where long-term soil potential monitoring is required. A Cu/CuSO₄ reference electrode is not the same as an anode. It is used for measurement and monitoring, while an anode provides protection current.
Important Note
Cu/CuSO₄ Reference Electrode ≠ Anode
