10kV digital high voltage Megohmmeter insulation resistance tester Electricians portable insulation resistance meter

The optical digital insulation resistance tester is developed using the Faraday effect of magneto-optical crystal, IE660044.7 and IEC61850 to produce an optical digital insulation resistance tester:

1. Optical digital insulation resistance tester will not generate radiation and electromagnetic pulse, strong anti-interference ability and accurate measurement data.

2. Since the light is an insulator, the high voltage can be effectively isolated (to ensure the personal safety of the operator), and the accuracy and reliability of the sampled data are ensured while suppressing noise.

3. Can cope with its harsh test environment.

4.5.7-inch large screen display, actual test voltage display, leakage current display.

5. True automatic discharge function, no need to manually discharge.

6. Short-circuit current 10mA Strong anti-interference ability.

7. High output power of the instrument, real-time voltage measurement (actual charged voltage of the sample), leakage current measurement, automatic discharge (discharge voltage measurement)
