Silver/Silver Chloride Reference Electrode

Application

Measure the potential with an ohmic component and the polarization potential without an ohmic component (protective potentials) of metal structures in circuits when determining the efficiency of corrosion protection of metal structures, as well as in system for automatic control and regulation of the operating mode of electrochemical protection installations.

The electrode is intended for placement in the engineering compartment and other enclosed spaces of the vessel, for operation in the following climatic conditions:

  • — relative air humidity (75 ± 3)% at temperature (45 ± 2)°С or (80 ± 3)% at temperature (40 ± 2)°С, and also at relative humidity (95 ± 3)% at temperature (25 ± 2)°С;
  • — rated operation high temperature is +45 °C;
  • — rated operation low temperature is 0 °C.
