Overview
The CerAnode™ Silver/Silver Chloride Underground Reference Electrode is a permanent Ag/AgCl reference electrode engineered for stable, long-term potential measurement in buried cathodic protection systems. Designed for underground infrastructure and permanent monitoring locations, the AG-AGCL-2 provides a reliable reference for pipe-to-soil potential measurements, CP system evaluation, polarization monitoring, and corrosion-control verification.
Built for demanding underground environments, the AG-AGCL-2 combines a stable silver/silver chloride reference system with a protected electrode assembly and soil-contact interface designed to maintain consistent electrical communication with the surrounding environment. Engineered backfill and moisture-retention provisions can help maintain stable electrode performance across varying soil conditions and extended installation periods.
Designed for integration into modern cathodic protection monitoring programs, the AG-AGCL-2 supports permanent test stations, pipeline monitoring systems, remote data acquisition, rectifier control systems, and automated CP monitoring networks.
