Tinker & Rasor Model CPV-4 Cathodic Protection Voltmeter is a revolutionary instrument for measuring DC structure-to-earth potentials of various buried or submerged metallic objects. Powered by an ordinary 9-volt battery, the Model CPV-4 gives an immediate reading in large ½...
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...
SAKOVA DC HV TEST SET has been designed to test the 11 KV & 33 KV cables, cable fittings, switchgears and high voltage installations. The desired DC voltages are applied to the “system” under test. The leakage current and the voltage applied are...
