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


Electrical installations testing:

The MIT400/2 includes all the features required for electricians and engineers working in a range of industries. Features are selected to make testing easy and fast in a range of situations. Typical industries include:

  Electrical supply companies
  Large and small scale electrical installation
  Periodic inspection and testing
  Cable testing

Service, repair and maintenance:

The MIT410/2 and MIT420/2 add additional features required for engineers working on more demanding applications. Functions such as PI and DAR, capacitance measurement and a greater range of test voltages increase the suitability for applications such as:

  Manufacturing/production testing
  Panel building
  Railway and other transportation
  Motor testing
  Cable inspection/quality control
  Street lighting maintenance
  Avionics ground testing and maintenance
  Military applications

MIT420/2 also includes 25 and 50 V ranges for testing communication circuits for signalling controls :

  Elevator service engineers
  Street lights (Pedestrian controls)
  Machines and saftey interlock/commisioning service
  HVAC controls
  Robotic Power and Control

Electrostatic discharge testing:

The ability to swap displays from kΩ, MΩ, GΩ to 10^5, 10^6, 10^7 and to vary the test voltage make the MIT420/2 and MIT430/2 ideal for ESD testing, including servicing of equipment and routine maintenance of ESD conductive flooring, bench mats and grounding systems etc. Typical industries include:

  Electronic manufacturing
  Electronic servicing and repair
  Calibration houses
