Megger MIT400/2 Insulation and Continuity Tester

The MIT400/2 is a competitively priced entry-level instrument with the capability to test insulation at 250 V, 500 V and 1000 V. It offers an enhanced fast continuity test feature, with auto-ranging for measurements from 0.01 Ω to 1.0 MΩ. Continuity tests can be performed at either 200 mA or 20 mA, to suit the requirements of the application. The instruments also offer voltage measurement up to 600 V AC and DC, with AC measurements being true RMS (TRMS). The MIT400/2 has a tough shock-absorbing rubber over moulding that provides excellent grip, and it also features weatherproof IP54 protection. In addition, the instrument has a bar at the top to allow the addition of future accessories, such as magnetic hanging straps and belt loops. ELECTRICAL INSTALLATION TESTING The MIT400/2 includes all the features required for electricians and engineers working in a range of industries. Features are selected to make testing easy and fast in a range of situations.
