Megger MIT320 Insulation and Continuity Tester

The Megger MIT320 is a Insulation and Continuity Tester designed for tough applications. The Megger MIT320 has a safety interlock system to prevent unsafe connection of test leads. It is rubber armoured and has a double hinge solid lid to protect the screen and fold away when the MIT320 is in use. It's also much safer thanks to having a switch placed on the test probe, meaning you can spend more time keeping your eyes on the job in hand.

All products in the MIT300 range offer automatic discharge of the circuit after testing, and also offer and audible and visual warning if the test probes are applied to a live circuit. The units also conform to IEC 61010-1 for use in Category III 600V applications.
