Megger MIT410/2 Insulation and Continuity Tester

The Megger 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. The stabilised insulation test voltage is now accurate to +2% -0%. This compares to the industry standard +20%, providing a more accurate test voltage without the risk of over-voltage damage to circuits or components. The output voltage is maintained between 0 & 2% throughout the test range. The MIT410/2 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. DUAL DIGITAL DISPLAY Large main digital readout for good visibility of all main measurement results. Second digital display for additional data such as: Insulation test voltage. Insulation leakage current. Supply frequency (when measuring volts). Test mode eg. PI, DAR or t ( t = Timer mode). FEATURES Stabilised insulation testing. 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.
