What is a Reference Electrode?

Copper-Sulphate Reference Electrode is used to measure the potential difference between a cathodic protection station and a protected metallic object.

EHZ-CENTER offers to buy Reference Electrodes and to deliver them.

Operating Principle and Diagram

The product’s work is based on oxidation-reduction reaction with copper and its salt (copper sulphate). Copper-Sulphate Reference Electrode is not polarized, i.e. it has a conducting capacity, i.e. its potential does not change.

Its typical diagram shows that the product consists of a copper rod inside a dielectric body which is filled with CuSO4 saturated solution (copper sulphate). The latter is separated from the soil with an ion-exchange membrane which is a porous screen and (or) a special ceramic filter. CuSO4 solution bleeds through a membrane, moistens it, and this membrane creates a galvanic contact between the rod and soil.

Occurred constant potential difference of copper-copper sulphate solution area becomes equal to the potential difference of a protected object — surrounding soil area with the devices.
