Overview
The Copper/Copper Sulfate Underground Reference Electrode is a permanent Cu/CuSO₄ reference electrode engineered for stable, long-term potential measurement in cathodic protection systems. Designed for buried infrastructure and permanent monitoring locations, the CS-CU-2 delivers accurate structure-to-electrolyte potential measurements for CP system evaluation, polarization monitoring, and corrosion-control verification.
Built for demanding field environments, the electrode incorporates a stable Cu/CuSO₄ reference system, porous ceramic junction, and moisture-retaining backfill technology to maintain reliable electrical contact across varying soil conditions. Its field-proven design supports consistent measurement stability in high-resistivity, dry, and variable-moisture environments where long-term signal integrity is critical.
Engineered for integration into modern CP monitoring programs, the CS-CU-2 supports test stations, remote monitoring systems, rectifier control systems, and permanent infrastructure monitoring networks.
