Bimetallic Reference Electrode


- Control of underground metal structures’ and mainline pipelines’ cathodic protection, as well as in the cathodic protection telemechanics and telecontrol systems.

- Measure of polarization potential by way of polarization current interruption.


Soil and long term operation in cathodic protection transducer control circuits working to ensure stabilization of the protected structure’s potential, high loads at great depth.
