Explosion explosion proof infrared moisture and thickness meter (Japan Stadnards)

Contact Us

IRMD is a pressure-resistant explosion proof specifications product of the infrared moisture and thickness gauge IM series.
It is a pressure-resistant explosion proof type that can be used in solvent specifications hazardous locations.
It is a moisture ・thickness meter that can measure moisture, organic content, film thickness, coating thickness, color density, etc., using the infrared absorption light that the measurement object has.
Using up to 10 wavelengths in the near-infrared to infrared wavelength range, it can measure a variety of constituent quantities.
In addition, up to 4 constituent simultaneous measurements can be made.

Real-time measurement of various constituent, moisture and thickness gauge using visible and infrared absorption

  • Measurements can be made even in explosion proof areas
  • Absorbance measurement possible for up to 10 wavelengths
  • Up to four constituent can be measured simultaneously
  • A wide range of models to suit the measurement target
  • high-speed and high sensitivity measurement, multi-computation
  • Easy maintenance design with self-diagnostic function

Other features

The compact design saves space, including the main body and explosion proof parts.
