Insulation resistance tester dedicated to the laboratory or on-site insulation test test. Contains high-precision micro-current measurement system, digital boost system. Only need to use a high voltage line and a signal line can be connected to the test sample measurement automatically, the results By the large-screen LCD display, and the results of storage.

First, the main features

1. Using 32-bit micro-controller control, the entire Chinese user interface, easy to operate.

2. Automatically calculate the absorption ratio and polarization index, and automatically store 15 seconds, 1 minute, 2 minutes, 10 minutes per minute data for easy analysis.

3. Output current is large, short circuit current is greater than 5mA.

4. Anti-interference ability, to meet the ultra-high voltage substation site operation.

5. Test the automatic discharge, and real-time monitoring of the discharge process.

6. Rechargeable battery and charger, when not using the backlight, fully charged can be used continuously for 6 to 12 hours.
