Megger MIT400 Insulation & Continuity Tester



The Megger MIT400 device performs insulation resistance measurements and continuity checks of electrical systems and cabling to verify integrity. Specifics on the MIT400 electrical tester:

  • It is a handheld, portable instrument that can be easily carried to job sites and electrical panels for testing.
  • It applies test voltages up to 1,000V to measure insulation resistance or leakage current in insulation materials and windings in motors, transformers, cables, etc. Common test voltages are 500V and 1,000V.
  • Insulation resistance testing helps determine if insulation has deteriorated or been damaged, indicating a potential for failure or shock hazard. Minimum resistance values indicate acceptable insulation levels.
  • The MIT400 measures insulation resistance up to 20,000 megohms. It displays the resistance reading directly in megohms on its digital screen.
  • For continuity testing, it sends a small current through a circuit or conductor and checks if current flows without resistance which would indicate a continuous path. This detects any breaks or damage in wiring.
  • Features include an analog arc display to see changing resistance trends and automatic measurement storage and recall.
  • Safety features such as protective silicone test leads, an auto-discharge function, and no exposed live parts make the MIT400 suitable for troubleshooting all sorts of equipment and wiring systems.

The Megger MIT400 is an advanced handheld instrument for measuring insulation condition and continuity of conductors, helping to identify faults and potential electrical issues. Its high 1,000V test capability makes it well-suited for preventative maintenance testing.

The  MIT400 series (Megger MIT400, Megger MIT410Megger MIT420 & Megger MIT430) replace the well-established BM400 insulation tester range.
