Digital Potential Meter

Model DPM Digital Electronic Potential Meter
For Electrolysis, Corrosion and Cathodic Protection Testing

Model DPM Potential Meter:

MODEL DPM DIGITAL POTENTIAL METER FOR ELECTROLYSIS, CORROSION AND CATHODIC PROTECTION TESTING…Designed for use by non-technical personnel. such as crews, service technicians, meter readers, etc., but also suitable for the most experienced engineers and staff.

Practically eliminates low potential readings caused by resistance in the external circuit due to contact resistance of the referenceelectrode. This condition is frequently encountered in city work and in frozen ground.
