IMT100

Industrial multi-tester

  • Exceptionally safe to use 
  • Complete suite of insulation resistance 
  • Ready for outdoor conditions 
  • Worry-free battery supply  
  • Full set of detachable test leads
  • Ideal for testing photovoltaic installations

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.
