Digital Tank Test Kit

4109 - M. C. Miller Company (MC Miller)

The voltmeter included in the kit, the “Model DPM” voltmeter, 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 special test lead that has a brass thumb screw on one end which allows the test lead to substitute for the RE-5 reference electrode. This substitution allows the voltmeter to take “structure-to-structure” potential difference readings. The voltmeter offers two ranges, ±2VDC and ±20VDC with a 20MΩ input impedance. Since the voltmeter is digital [in contrast to the meter in our analog tank test kit (Cat. # 4108)], both negative and positive voltages are displayed. `
