Product Overview

The MIT420/2 from Megger is a MIT400 series CAT IV insulation tester with polarisation index (PI), dielectric absorption ratio (DAR) functions, variable test voltage range (VAR) and result storage. It is designed not only for electrical and industrial testing but also for exceptionally wide range of applications from electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance. Insulation testing has been enhanced with feedback controlled test voltages to limit overvoltage to 2% rather than industry standard 10-20%. A variable range has been added to allow any intermediate voltage from 10V to 1000V in 10V steps where application specific test voltages are required that do not appear in standard ranges. It has redesigned weatherproof tough housing, back stand & 6 cell battery compartment with separate fuse access. The dimension is 108mm x 228mm x 63mm (W x D x H) and weight is 600g. It operates -10°C to +55°C temperature.
  • 50V, 100V, 250V, 500V and 1000V insulation test voltage and 200Gohm range
  • Stabilised insulation test voltage, live circuit detection and protection
  • Single range, faster continuity testing from 0.01ohm to 1Mohm
  • 600V TRMS AC and DC voltage measurement, 0.25Mohm input impedance
  • Test inhibit, insulation buzzer, test lock, lead null and buzzer
  • CAT IV 600V / CAT III 1000V & IP54 rated, meets international requirements of IEC61010 and EN61557
  • Auto power down (setup), auto reverse polarity (setup ON-OFF), 15Hz to 400Hz frequency measurement
  • 2% test voltage accuracy, pass/fail indication, test voltage, measurement range and voltage display
  • Display offers a combination of analogue arc and dual digital readout
  • 0.1nF to 10μF capacitance range and onboard memory
