Million Megohm Meter
Model : Insulations Testers

This series of Million Megohm Meters are designed to test electronic components such as paper Capacitors, Plastic Capacitors, Ceramic Capacitors, Insulators, Semi Conductors, Switches, Connectors, transformers, Motors etc. as per I. S. I. recommendations.

The instruments have facility for checking insulation resistance in the range of 1 meg ohm to 10 million meg ohm after one minute of charging. Ultra stabilized power supply (.001% short term drift) permits measurements of intrinsic value of insulation resistance if required, even with capacitive loads. Separate push button controls and visual indicators for "Charge", and "Discharge" function are ideally suited for rapid and safe testing of components in a factory. Maximum output current has been limited to safe value to eliminate the risk of serious shock to operators. The instruments are available in five models as per specifications given overleaf.


  • Push Button Controls for rapid testing.
  • Tests as per I. S. I. recommendations.
  • Wide measurements range
  • Fully protected against all overload
    and short circuits.
  • Completely solid state circuitry, hence
    drift free operation.
  • Guard Terminal provided.
  • Suitable for testing ' EARTHED' Samples.
  • Suitable for testing insulation liquids (Resistivity measurements) with oil cell as per IS : 335
