Hand Driven Generator Insulation Meggers Tester

This is a compact, portable self-contained Instrument which is used for direct reading of insulation resistance of electrical installations and apparatus. The Insulation tester is composed of a hand driven A.C. generator and a high sensitivity cross-coil Indicator. The indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation, caused by irregular cranking have no influence on the results of measurement. The AC Magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in DC generators. The quick response saves the time and extend the life of the generator. Available in various ranges from 10 to 500 Mega Ohms.
