M.C. Miller Analog Potential Meter Kit
Item Number: 4107
The Model IA voltmeter (Analog 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 a 0 - 2 VDC range with a 10 MΩ 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 0.85 V (850 mV) threshold value.
Note: Only positive voltage values are displayed
Includes:
RE-5 reference electrode (Item #15108)
8 ft black test lead with 46-C clip (Item #SUB174)
Orange Case with Padding (Item #4115)
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)
