Questions about this product? ↗The STAPERM™ AG-3-SW is a permanent silver/silver chloride reference electrode for seawater cathodic protection monitoring. Its color-coded housing and integral lead provide a dedicated reference point for potential measurements.
Technology and construction
A porous ceramic contact plug forms the sensing interface with the water, while the high-impact ABS tube protects the reference assembly. The integral lead connects the submerged electrode to an accessible measurement point for ongoing cathodic protection checks.
Key advantages
- Dedicated submerged reference: A fixed installation lets operators return to the same reference location for routine measurements.
- Ceramic contact technology: The porous plug provides ionic contact between the reference electrolyte and the surrounding water.
- Practical installation: The integral lead and color-coded housing support straightforward connection and chemistry identification.
- Seawater chemistry: Silver/silver chloride is the specified chemistry for this model’s saltwater and high-chloride water service.
Applications
Seawater docks, submerged pipelines, offshore structures and other saltwater cathodic protection monitoring locations.
