China High Quality harga megger Factories – GD2000D Insulation Resistance Tester – HV Hipot
China High Quality harga megger Factories – GD2000D Insulation Resistance Tester – HV Hipot Detail:
General Information
GD2000D digital insulation resistance tester produced by our company uses an embedded industrial single chip real-time operating system. The digital analog pointer and digital field code display are perfectly combined. This series of meters has a variety of voltage output levels (250V, 500V, 1000V, 2500V, 5000V, 10000V), large capacity, strong anti-interference, analog pointer and digital synchronous display, AC and DC dual-use, simple operation, automatic calculation of various insulation indicators (absorption ratio, polarization index), various measurement results with anti-power-down function, etc. It is an ideal test instrument for measuring the insulation resistance of large-capacity transformers, transformers, generators, high-voltage motors, power capacitors, power cables, and lightning arresters.
