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.
