Analog Tank Test Kit

4108 - M. C. Miller Company (MC Miller)

The voltmeter included in the kit, the “Model IA” 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 a 0 - 2VDC range with a 10MΩ input impedance and the analog display presents a color divided scale for convenient indication as to whether or not a carbon-steel structure is receiving a suitable level of cathodic protection, with respect to the accepted 0.85V (850mV) threshold value.
