Analog Cathodic Protection Voltmeter
- The Tinker & Rasor Model CPV-2 Cathodic Protection Voltmeter is an extremely rugged new instrument for measuring the DC structure to earth potentials of various 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 meg ohms (10 million ohms) of this instrument results in potentiometer quality voltage readings. Red-is-bad and green-is-good segments with 0.85 V as the division line.
- 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.
