About Insulation Testers 400/2 Series
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.Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry standard 10-20%.A variable range has been added to allow any intermediate voltage from 10 V to 1000 V in 1 V steps, where application specific test voltages are required that do not appear in the standard ranges.*Continuity testing is now significantly faster, and a single auto-ranging 0.01 to 1.0 M function replaces the ohms and kOhms ranges. Retained are the 200 mA and 20 mA test options
Advanced Display and Measurement PrecisionEquipped with a large, backlit LCD screen, the Insulation Testers 400/2 Series offer excellent readability even in low-light environments. With selectable test voltages and measurement range extending up to 200 G for insulation resistance, you can execute tests confidently, benefiting from 2% accuracy during diagnostics or maintenance projects.
Durable and User-Friendly DesignEncased in high-impact plastic with IP54 and drop-resistant features, this tester endures demanding field conditions. The ergonomic, compact construction, along with the supplied carry case, ensures easy portability. Auto-discharge, overload protection, and a robust lead set assure safe operation and minimize the risk of instrument damage.
Versatile Application and ComplianceIdeal for professionals working in electrical installation, equipment servicing, and routine safety checks, the MIT400/2 Series is rated for CAT IV 600V and CAT III 1000V, meeting IEC 61010-1 standards. Its multifunctional capabilities-insulation testing, voltage measurement, and continuity checks-make it an essential tool for electricians and maintenance engineers.
FAQ's of Insulation Testers 400/2 Series:
