The Megger MIT330 Insulation Tester EN helps you prove insulation and continuity with simple steps and strong safety. You move from board to board with steady results and easy control.

Performance for daily testing

You work with three insulation test voltages and a wide reading up to 999 megaohms, so faults show up early and clearly. A 200 mA continuity test with a sharp buzzer speeds up checks, while the IP54 case handles dust and splashes on busy jobs.

Practical tools that save time

You can store results on the instrument and send them by USB when the job is done, which keeps records neat and tidy. A default voltmeter to 600 volts, a switched probe, and a backlit display make live work areas easier to manage without fuss.

You stay safe with live circuit warnings and test inhibit when supply is present, which helps prevent errors. Strong build and a folding hard cover protect the screen and controls and keep the kit ready for the next test.
