Megger MIT320 – Refurbished  – Used – Second hand


Megger MIT320 Insulation tester.

This Megger MIT320 1kV Insulation tester has been refurbished to like new condition, according to the factory standards using original Megger parts.

The Megger MIT320 features the popular Megger digital/Analogue display. Large 20mm high characters provide very clear readout, combined with an analogue arc for the feel of an analogue instrument, with a true analogue response. The meter is extremely easy to use and has a tough rubber armoured case and self contained protective cover. It has live circuit warning and Intelligent Safety System for protection and is weatherproof to IP54 standard.

Unit Includes:

  • Original carry case.
  • Carry strap.
  • Original test leads & crocodile clips.
  • Original documentation.
  • NON-SANAS 12 month calibration certificate (a SANAS certificate can be arranged at an additional cost to the buyer).
