Product Detail


It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. The digital insulation resistance meter is composed of medium and large-scale integrated circuits, including a high-precision micro-current measurement system, a digital boost system, and an automatic discharge circuit. You only need to connect the DUT with a high-voltage line and a signal line to measure.The rated output test voltage range is 250V~5000V, and the insulation resistance measurement range is 0.01MΩ~5.00TΩ. The DC voltage measurement range is 0V~1000V DC, and the AC voltage measurement range is 0V~750V AC.
