Non-destructive measurement of component in fish/meat using near infrared light

Mobile Near-infrared component analyzer

View Product Brochure

Non-destructive component measurement irradiating near infrared light (dual wavelength) into the object.
By connecting with PC or mobile PC via USB interface (wired) or Bluetooth (wireless) enables to obtain the signal from each wavelength.
The component of object can be measured based on the first/second differentials of each wavelength.


  • 1. Component analysis by absorption measurement in the near infrared region
  • Non-destructive component measurement irradiating near infrared light (dual wavelength) into the object.

  • 2. Compact and lightweight by ultra small sensor
  • Having wireless connection by Bluetooth to PC or smartphone makes the measurement easy without fixtures such as cables and power supplies.

  • 3. Oil/Fat component analysis of fish/meat
  • Applicable fishes: Trachurus japonicus,chub mackerel, Blackthroat seaperch, Whitespotted conger, Fillet, etc.


(Detection of foreign materials, analysis of sugar content in fruits and fat and oil fat of components in meat and fish)
