  • CAT IV 600 V & IP54

The MIT400 mk2 series insulation and continuity testers are designed not just for Electrical and Industrial, but with an exceptionally wide range of applications from electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance etc.

Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry standard 10-20%.

A variable range has been added to allow any intermediate voltage from 50 V to 1000 V in 10 V steps, where application specific test voltages are required that do not appear in the standard ranges.

Continuity testing is now significantly faster, and a single auto-ranging 0.01 Ω to 1.0 MΩ function replaces the “ohms” and “kOhms” ranges. Retained are the 200 mA and 20 mA test options.

Replacing the original MIT400 instruments the new units feature a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access. All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating.

The range consists of four instruments:
MIT400/2            250 V, 500 V and 1000 V
MIT410/2            50 V, 100 V, 250 V, 500 V and 1000 V + Polarisation Index, Dielectric Absorption Ratio
MIT420/2            50 V, 100 V, 250 V, 500 V and 1000 V + Polarisation Index, Dielectric Absorption Ratio, Variable Test Voltage and result storage
MIT430/2            50 V, 100 V, 250 V, 500 V and 1000 V +Polarisation Index, Dielectric Absorption Ratio, Variable Test Voltage and Bluetooth download

Download Manager

Welcome to the latest issue of Download Manager, the free of charge software that allows you to down load information from selected Megger instruments, read the information in an easy to understand format , store it in a Windows file system and draw graphical representations of the data.


This latest issue of the software is easily identifiable as the name of the programme is "Megger Download Manager" -  all previous issues were called "AVO Download Manager". Previous AVO version instrument drivers are not compatible with the new programme - however all previous data files (stored as .CSV files) are fully compatible so there will be no problems in reviewing previously stored data gathered using older versions of software. In addition, all Megger instruments supported by the AVO Download Manager have new drivers written for Megger Download Manager, making upgrading simple.
