Overview
The CRE-AG-7 IR-Free Reference Electrode is a precision silver/silver chloride (Ag/AgCl) reference electrode engineered for accurate structure potential measurement in impressed current cathodic protection (ICCP) systems. Designed to minimize IR drop error during CP testing, the CRE-AG-7 provides reliable polarized potential measurements for evaluating true structure protection levels and system performance.
Built for long-term deployment in buried, submerged, and exposed monitoring environments, the CRE-AG7 combines stable Ag/AgCl reference chemistry with a sealed housing and controlled ionic junction to deliver dependable measurement stability in demanding field conditions. Its low-noise, low-polarization design supports accurate “instant-off,” polarized, and depolarized potential measurement where conventional reference readings may be influenced by voltage gradients or stray current interference.
Engineered for integration into advanced CP monitoring programs, the CRE-AG7 supports permanent monitoring installations, AC mitigation systems, remote monitoring networks, marine infrastructure, and critical asset integrity programs requiring high-confidence polarization data.
