Megger MIT2500 Hand-Held High Voltage Insulation / Continuity Tester

The Megger MIT2500 is a combined Insulation and continuity testers designed for industrial maintenance and electrical contractors boasting a lot of power in a very small and convenient package, performing insulation tests with a test voltage up to 2500 V, and measuring insulation resistance up to 200 GΩ.

The MIT2500 is a tough, CAT IV, 600V 3–wire tester using the well-established Megger guard terminal technology to ensure that surface leakage is discounted when making a measurement.


Megger MIT2500 is perfect for:

  • Commercial Avionics
  • Military land, marine and air communications
  • Manufacturing/production line goods
  • Electrostatic measurement
  • Component testing
  • Battery-powered traction and lifting equipment
