Megger MIT300 Insulation and Continuity Tester

The Megger MIT300 is a Insulation and Continuity Tester designed for tough applications. The Megger MIT300 has a safety interlock system to prevent unsafe connection of test leads and stop insulation testing when circuit voltage is greater than 50V. The Megger MIT300 also stops continuity testing on Live circuits thanks to the safety lockouts. It is rubber armoured and has a double hinge solid lid to protect the screen and fold away when in use. Safer test equipment means less thinking, so you can spend more time keeping your eyes on the job.

The unit fully conforms to IEC61010-1 for use in Category III 600V applications, and provides all of the facilities that are required to meet testing requirements. All products in the MIT300 range offer automatic discharge of the circuit after testing has concluded, aswell as an audible and visual warning if the test probes are applied to a live circuit.
