Various Applications

  • IR-CAN for polyester film
    Highly accurate measurement is available by using polyester polymer peculiar absorption band.
  • IR-CAM for polyethylene film
    Highly accurate measurement is available without affected by film thickness and coloring agent by using absorption band for hydrocarbon contained in polyethylene polymer.
  • IR-CAR for inside furnace
    The thermometer is suitable for measuring the temperature of an object inside a furnace and an object directly heated by a burner. Highly accurate measurement is available without affected by combustion gas.
  • IR-CAG for glass
    Temperature of glass surface can be measured accurately without affected by permeation or reflection by using the particular wavelength which has less glass transmittance and influence of water vapor and CO2.
  • IR-CAT for silicon
    Temperature of a wafer can be measured accurately without being affected by the heater on the back of the wafer by using opaque wavelength band of infrared light to silicon (measuring wavelength which is absorbed by silicon).
  • IR-CAU for gallium arsenide
    Temperature of a wafer can be measured accurately by using opaque wavelength band of infrared light to gallium arsenide (measuring wavelength which is absorbed by gallium arsenide).
  • IR-CAF for Food Industry AF
    The thermometer can measure liquid temperature right after fruits or vegetable beverage filled a can/bottle by high-speed and highly accurately.
  • HMD (Hot metal Detector) IR-CADAC01
    It is an exclusive device for judging the existence of metal heat mass such as aluminum. When a hot mass above the detection level is detected, the output is turned ON.
