The plate indicator block is intended to assess the current state of corrosion and to monitor the effectiveness of cathodic protection equipment for underground steel structures.
PTI.KMG marks in the field the intended point for installation of a portable copper sulfate reference electrode when measuring the protective potential of underground steel pipelines and structures. It provides protection of the measurement point from debris, stones, and atmospheric precipitation.
Reference electrodes are used in cathodic protection systems against corrosion and serve to measure polarization and total potentials on underground steel pipelines and structures.
