Megger MIT330 Insulation and Continuity Tester
The most advanced overall model in Megger's MIT330 series, this comprhensive tester includes everything you'll need for testing both insulation and continuity.
Insulation testing can be performed at selectable test voltages of 250, 500 and 1000V with a built-in insulation limit alarm from 0.01MΩ to 999MΩ. Continuity testing can be performed across a wide range with an adjustable buzzer (and the option to disable) and dedicated voltage and resitance measurement functions are also included.
Megger's MIT330 is the only model in the MIT300 series which comes with internal memory and download to PC. This makes it significantly easier to manage and view back measurement data without the hassle of jotting everything down in a pad.
A number of other additional features are also included such as a built-in voltmeter, backlit display, locking test button and a protective cover for the unit when not in use.
