Suitable for use with both new build and existing structures, the CPMP is installed adjacent to the protected structure and contains a permanent internal reference electrode encased in a steel coupon. This innovative design shields the reference electrode from external interference and provides an error free and highly accurate reading of structure potential, current density and polarization decay.

The CPMP-3 is our newest version of the CPMP series and incorporates class leading upgrades that improve durability and lower cost. When used in conjunction with the Corrosion Service ZRA zero resistance ammeter, the CPMP provides an indication of current density and further validation of corrosion protection system operation.

The Corrosion Service Portable Transformer Rectifier Unit (TRU) is one of the most essential tools in the cathodic protection technician’s tool box. The TRU allows a variety of surveys to be performed where they would not otherwise be possible by supplementing, mimicking, or replacing permanent cathodic protection installations. Common applications include coating holiday (DC voltage gradient) and current requirement surveys. The TRU provides high output voltage, allowing the generation of significant test currents even under high resistivity soil conditions. The unit is air-cooled with a continuously variable variac control and is conveniently fitted with an interrupter interface. Standard units are supplied with LED displays in a painted carbon steel cabinet, which is rugged enough to withstand demanding field conditions.
