HD3122 Insulation Resistance Tester is suitable for measuring the resistance of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. Digital insulation resistance meter is composed of medium and large scale integrated circuits, including high-precision micro current measurement system, digital boost system and automatic discharge circuit. Only a high voltage line and a signal line are needed to connect the measured the test object to measure.
It can automatically calculate the absorption ratio(DAR) and polarization index(PI), and automatically store the data of 15 seconds, 30 seconds, 1 minute and 10 minutes.
