The Megger insulation testers will take the bashing that testers receive when they are on site

They are rubber armoured and have an integral solid lid to cover the display. The lid has a heavy-duty hinge that locks away underneath when in use, making it easy to use and impossible to lose. And you don’t need to pull out the test leads to shut the lid.

The Megger MIT insulation testers are easy to use and quick to learn

There are no buried functions, so it is easy to use these new insulation testers. The colour coding helps test selection, speeding up testing time and helping you identify faults fast. The quick start guide in the lid keeps all the basic information at hand if you need it

Your safety is Meggers number one concern. These safety features look after you and the tester

• Safety interlock to prevent unsafe connection of the test leads
• Safe contact detector keeping you and your tester safe during continuity testing if it’s accidentally connected to a live circuit
• Live voltage warning alerts the user to a circuit voltage over 25 V when insulation testing
• Safety lockouts
  • Prevents continuity testing on live circuits
  • Prevents insulation testing when circuit voltage is greater than 50 V

Hands free operation

MIT300 series insulation testers are well balanced to hang comfortably around your neck enabling hands free operation when you need it. The continuity test and buzzer start automatically when you connect to a circuit, saving you time. Insulation tests can be started using a switched probe or the test button on the front of the tester.

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

A versatile handheld multi-testing instrument with more than 13 distinctive testing features

Get a unique instrument capable of testing resistance, continuity, and insulation resistance in systems, combining the two, three and four-terminal methods

The IMT100 industrial multi-tester is a versatile instrument with a complete suite of insulation and low resistance testing capabilities, plus continuity, inductance, capacitance, voltage, and temperature measurements.  

Additionally, the instrument can test insulation resistance from 100 Ω up to 200 GΩ, with test voltages of 50 V, 250 V, 500 V, 1 kV, and selectable variable voltage.  The instrument includes a guard terminal, and supports several diagnostic insulation resistance functions including spot reading, polarisation index ratio, and timed insulation testing.

The IMT100 comes with a unique four-wire digital low resistance function that includes a stable power supply that can deliver 200 mA in long circuits with a resistance range from 1 mΩ up to 10 Ω. This unit offers different test modes selectable through a soft keypad, including bidirectional, unidirectional, automatic, and continuous. The rotary switch and soft keypads are easy to operate, with or without gloved hands, and the instrument’s full colour graphic display makes it easy to select functions and take readings.

The unit also has a supplied thermocouple (CAT III to 600 V) that enables you to test temperature and insulation resistance compensation.  

What’s more, the LRC function allows the IMT100 to automatically determine if the main element of the load is inductive, capacitive, or resistive, and displays the result on screen. It also gives you the ability to select each function and frequency to 120 Hz or 1000 Hz.

The IMT100 comes with data storage management for up to 256 test results with individual tag names and dates. These can be downloaded to a USB drive and are also accessible within the instrument via a dedicated colour-guided recalling test results dashboard.

This instrument is designed to be exceptionally safe to use. The fast-detecting circuitry reduces the likelihood of damage to the instrument if accidentally connected to live circuits or across phases.

Occasional software updates may be issued on the Megger website, and the instrument can be updated by simply connecting a USB drive to the IMT100 with the firmware update file in the root directory. The IMT100 will start the update process automatically.
