Extech MG310 Digital Insulation Tester

This compact, lightweight testing instrument is made for quick and easy testing and troubleshooting of motors, transducers and other industrial appliances.

Simple to use, the Extech MG310 tests insulation with selectable test voltages of 250, 500 and 1000V. Insulation resistance can be measured up to 5.5GΩ and it is also possible to use this insulation tester to measure AC voltage from 30 to 600V and to test polarisation index (PI) and dielectric absorption ratio (DAR).

For added safety while testing, the Extech MG310 has high voltage/overload indicator and will automatically discharge itself after the test. An additional voltage output warning is also included.

Additional functions of this insulation tester include a low resistance measurement mode with zeroing function, continuity beeper, large-size digital LCD screen with backlight and more. The tester is also supplied as standard with a hard protective cover, ensuring the tester is protected during transportation.
