WHDY30 Intelligent Analogue Display Insulation Resistance Tester adopts embedded industrial single-chip Real Time Operating System,adopts extra-thin tensile-spring header perfect assembled with LCD . 

It with various output voltage (500V,1000V), high capacity, strong anti-interference ability, pointer display synchronously with data , applies to DC and AC, easy to operate, calculates the insulating index ( absorptance, polarization index), results automatically, without power failure, etc.

It is the ideal equipment to test large-capacity transformer, mutual inductor, generator, HV electric motor, power capacitor, cable, lightning arrester and so on.

1.Kinds of output voltage : WH3125 (500V/ 1000V/ 2500V/5000V), the measured resistance range 0~200GΩ, auto shift the measurement range, and with corresponding indications.

2. Pointer display synchronously with data display the insulation resistance data.

3.With LCD, auto shift the measurement range.

4. Adopts embedded industrial single-chip Real Time Operating System, high capacity, strong anti-interference ability.

5. Friendly operation interface, results without power failure, can save results of 20 tests.

6. There will be warning tone if the device engender high voltage.

7. Built-in residual HV discharge circuit, can auto discharge the residual high voltage on of the measured equipment after the test.

8. Applies to DC & AC, equipped with rechargeable battery and AC adapter.

9. Portable design, convenient for field tests.

10. HV short circuit current≥3mA, it is the ideal equipment to test large-capacity transformer, mutual inductor, generator, HV electric motor, power capacitor, cable, lightning arrester and so on.
