DMG Digital Megohmmeter
Apply to checking the insulation resistance of electrical equipment or circuit to ground and phase to ensure that the equipment works properly. Output voltage level 100V,250V, 500V,1000V,2500V,5000V. It can effectively shield the external power frequency and strong electromagnetic field.
Introduction

Apply to testing the performance of insulation resistance between electrical equipment or wire to ground, to make sure the equipment run normally.

Digital insulation resistance meter also known as megohm meter, high voltage insulation resistance tester. This instrument has LCD big screen grey and white backlight display, data storage, data checking, alarm, automatic shutdown and other functions.

Features
1、Can choose different output voltage,The measuring resistance range is up to 0~400GΩ;
2、Dual display insulation resistance value. Pointer and digital display.
3、Adopt real - time operating software system and single chip system. High degree of automation, strong anti-interference ability, the instrument can automatically save the test results, without manual intervention;
4、Friendly operation interface, various measurement results with anti-power function, can continuously store 19 measurement results;
5、When high voltage generating, there will be prompt sound output and corresponding display;
6、Can use ac and DC, with rechargeable batteries and AC adapters;

7、Adopts portable design, easy to operate in the field;

8、High voltage short circuit current ≥1mA, it is an ideal test instrument for measuring insulation resistance such as transformer, generator, high voltage motor, power capacitor, power cable, lightning arrester, etc.
