The DPM voltmeter (Digital Potential Meter) is designed for ease of use by meter readers and corrosion technicians alike. The voltmeter includes an integrated RE-5 reference electrode attached for "metallic structure-to-soil" potential difference readings. The kit also includes a test lead for electrical connection to a metallic structure.
The voltmeter offers two ranges, ±2 VDC and ±20 VDC with a 20 MΩ input impedance. Since the voltmeter is digital, both negative and positive voltages are displayed.
- RE-5 reference electrode
- 8’ red test lead with 46C clip
An optionally available electrode extension can be used to eliminate having to bend over to have the reference electrode placed in contact with soil. See the M.C. Miller 30 inch Electrode Extension.
