The silver/silver chloride reference electrode is used to measure the potential of seawater structures and concrete structures. The inside of the electrode is composed of silver powder/silver, silver nitrate, hydrochloric acid, and silver chloride. The reference electrode can be exposed to seawater or immersed in a silver chloride solution contained in a gas cylinder. There is a porousplug at the bottom.

Portable silver/silver chloride reference electrode for temporary measurement of structure-environment potential; stationary silver/silver chloride reference electrode for long-term structure-environment potential detection.
