The Tinker & Rasor Model CPV-2 Cathodic Protection Voltmeter is an extremely rugged instrument for measuring the DC structure-to-earth potentials of buried or submerged metal structures.
Powered by two "AA" penlight cells, the Model CPV-2 requires no push to read switch, and the solid state integrated circuit has built-in filter to reject AC interference. Input resistance of 10 megohms (10 million ohms) of this instrument results in potentiometer quality voltage readings.
This versatile meter may also be used without the reference electrode to measure direct current potentials from 0 to 2 Volts, such as potentials across an insulated flange, anode-to-structure, or structure-to-structure.
