Model I.A. Analog Potential Meter by M.C. Miller

The Model IA voltmeter (Analog Potential Meter) is designed for ease of use by meter readers and corrosion technicians alike and 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 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

• RE-5 reference electrode
• 8 ft black test lead with 46-C 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.
