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.
Study the features and specs and you'll see why corrosion
experts agree that the Model CPV-2 offers greater benefits.
