Megger MIT420/2 Insulation and Continuity Tester

The MIT400 mk2 series insulation and continuity testers are designed not just for Electrical and Industrial, but with an exceptionally wide range of applications from electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance etc. All primary results are displayed in the larger digital display and repeated on the analogue arc. Auxiliary test information such as frequency, leakage current, insulation or circuit voltage is displayed in the smaller secondary digital display. The MIT420/2 adds additional features required for engineers working on more demanding applications. Functions such as PI and DAR, capacitance measurement and a greater range of test voltages increase the suitability for applications such as: manufacturing/production testing, panel building, railway and other transportation, motor testing, cable inspection/quality control, street lighting maintenance, avionics ground testing and maintenance, military applications. The MIT420/2 also includes 25 and 50 V ranges for testing communication circuits for signalling controls: Elevator service engineers. Street lights (Pedestrian controls). Machines and saftey interlock/commisioning service. HVAC controls. Robotic Power and Control. FEATURES Stabilised insulation testing. Variable 50V to 1000V test voltage. Auto hold on continuity tests. Analogue arc with pointer. 200Gohm test range. Continuous continuity range. Rechargeable options. Contoured ergonomic design. Increased battery life. IP54 ingress protection. CAT IV safety design. 600V measurement.
