All new M.C.Miller meters include a Calibration Certificate
The DPM voltmeter (Digital Potential Meter) is designed for ease of use by meter readers and corrosion technicians alike and the voltmeter comes with 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 (Item #15108)
- 8’ red test lead with 46C clip (Item #SUB172)
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, for example, our 30 inch Electrode Extension (Item #16203).
