We offer precision A.C. Milli-voltmeter very useful in general laboratory and R&D labs. AC Milli-voltmeter is a very versatile instrument of accurate measurement of low signal like microphone outputs, Amplifier frequency response, RMS voltage...
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...
