Portable Reference Electrode


Measure potential drop between underground structure protected by way of cathode polarization and the soil.

General Description

The electrode consists of an electrolytic chamber filled with blue copper, and a copper core connected to the tip by a cable outlet. In the bottom part of the electrolytic chamber there is a tip in shape of a plug with porous structure.
