Megger MIT420 Insulation & Continuity Tester



Designed for electricians, the MIT420 insulation and continuity tester can perform electrical testing for utilities, industrial, commercial, and domestic applications.

It’s also designed for maintenance and service engineers. The Megger MIT400 series models, including MIT410, MIT420, and MIT430, replace the prior BM400 insulation testers. The new MIT420 provides greater functionality, simplified use, expanded apps, and increased safety.

The MIT420 circuit tester brings key advantages –

  • Category IV 600V safety ratings for diverse troubleshooting service
  • Residential wiring to heavy commercial equipment testing range
  • True RMS & DC voltage detection measurements
  • Insulation resistance testing to 20 GΩ for sensitive leaks
  • Continuity testing as low as 0.01Ω to catch contact issues early
  • Built-in pass/fail limit alarms to increase testing efficiency
  • Dual digital & analog readings for clear reliability testing results
  • Ruggedized portability at 1.75 kg for field maintenance

The Megger MIT420 insulation & continuity tester kit includes-

  • MIT420 circuit testing unit
  • Heavy-duty protective case
  • Test leads up to 600V safety rated
  • Red & black 1.25m probes with croc clips
  • Leadership calibration certificate
  • MIT420 tester boot for drop protection
  • Detailed owner’s information guide

With preventative maintenance features like adjustable test voltages from 250V to 1000V, the versatile MIT420 allows electricians and technicians to conduct predictive insulation deterioration and continuity fault testing across electrical motors, transformers, cables, switchgears, domestic circuits, and more. By identifying issues early on, electric shock and equipment failures can be avoided down the line.

The  MIT400 series (Megger MIT400, Megger MIT410, Megger MIT420 & Megger MIT430) replace the well-established BM400 insulation tester range.
