Model DPM
Digital Electronic Potential Meter
by MC Miller Co.
For Electrolysis,
Corrosion and Cathodic Protection Testing.
| Model DPM
Potential Meter Designed for use by
non-technical personnel, such as crews, servicemen, meter readers, etc., but also suitable
for the most experienced engineers and technicians.
20 megohms input resistance practically
eliminates low potential readings caused by resistance in the external circuit due to
contact resistance of the reference electrode. This condition is frequently encountered in
city work and in frozen ground. |
