Portable Silver/Silver Chloride Reference Electrode

The silver-silver chloride (Ag/AgCl) electrode, sometimes referred to as “SSCE”, is a type of reference electrode, commonly used for testing cathodic protection corrosion control systems in sea water environments. This Ag/AgCl reference electrode can be exposed to seawater or immersed in a silver chloride solution contained in a gas cylinder.

A reference electrode is used to measure the potential of seawater structures and concrete structures. The electrode is composed of silver powder/silver, silver nitrate, hydrochloric acid, and silver chloride with a porous plug at the bottom.

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



  • Easy installation, reliability and excellent anti-interference performance.
  • Small size, light weight, stable performance and strong corrosion resistance.
  • The electrode potential is stable.
  • A sintering process is utilized to overcome the disadvantages which can be found; such as easy falling off and short life of the pressed electrode.
