Megger MIT310 Insulation and Continuity Tester gives fast checks on fixed wiring with simple controls and clear feedback. It suits daily work on domestic and commercial sites where speed and safety matter. You read values on a crisp digital display with an analogue arc that helps you judge trends. You move between tests without fuss and keep a steady pace on every board.

Precision and safety

You apply 250 V, 500 V or 1000 V insulation tests across a wide resistance range and see steady results. You also run continuity tests with a strong test current that proves low resistance bonds with confidence. Live warning and test inhibit protect you from unsafe starts on energised circuits. A default voltmeter wakes when it senses voltage so you can verify conditions before you proceed.

Built for site work

You carry a tough, rubber-armoured unit with weather protection for dusty plant rooms and busy risers. You hang it with the strap for hands-free use and keep moving while the auto power save preserves batteries. Automatic discharge after insulation tests helps you finish safely. Clear prompts guide you so you stay focused on the job.

You can store the kit in the supplied hard case and keep leads tidy between jobs. You also receive a calibration certificate for compliance needs. The three year warranty backs long service in the field. This keeps downtime low and makes the tester a reliable choice for maintenance teams and installers.

Key features
  • Runs insulation and continuity checks in one compact unit for faster workflows
  • Shows results on a digital display with an analogue style arc for quick trend reading
  • Acts as a voltmeter when it detects live voltage so you can verify before testing
  • Warns on live circuits and blocks unsafe tests which supports safe isolation practice
  • Uses a strong continuity test current for confident bonding checks on low resistance runs
  • Gives a fast continuity buzzer that speeds up fault finding on large boards
  • Lets you null test leads so small resistance is removed from your reading
  • Locks the test button so you can keep a steady hold while recording values
  • Saves batteries with automatic power down during idle periods on site
  • Works in tough spaces with a rubber-armoured case and IP54 protection
  • Hangs on a neck strap for hands-free operation in cramped panels
  • Ships with a calibration certificate that supports audit and compliance checks
