Tester HT7050 is intended for the high-precision and reliable measurement of insulation resistance. These are light before the use instrument is made it possible make it possible to conduct measurements with the stress from 500 to 5000[V], controlling all parameters (insulation resistance, stress, the time of measurement). Instrument widely is used for measuring the insulation resistance of the revolving machines, transformers, isolation of systems with the high voltage, electros-cable.
