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...
The large scale integrated circuit has a built-in filter to reject AC interference. Input resistance of 11 megohms (11 million ohms) yields potentiometer quality voltage readings, and digital readout eliminates interpolation of voltages. This small, lightweight instrument needs...
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...
