The IR-FA series is a fiber optic radiation thermometer featuring multi-function and high-speed response.
Three types are available: IR-FAI single-color type for low temperature, IR-FAS single-color type for medium/high temperature and IR-FAQH series two-color radiation thermometers use two-wavelength system not being affected by emissivity or gray extinction and cover the high temperature of 500 to 3000 Parameter setting function, signal modulation and analog output are built in. 
Various options including lens assembly with finder, laser spotting function, analog input and communications interface are available.


  • Low temperature type with high-speed response (10ms) and short wavelength enables to measure objects with low emissivity such as metals.
  • Medium/high temperature type with high accuracy (±0.5 to 1% for 1000 to 2000ºC) and high-speed response (10ms) is for various temperature measurement fields.
  • Two-color type is stable with less effectiveness of smoke, vapor, dust and lack-of-view.
  • By using heat-resistive fiber optic, measurement in environment at 150ºC is possible without any water-cooling.
  • By signal modulation function, the stable temperature measurement is possible
  • Laser function for easy spotting of measuring point (option)
  • Emissivity setting (emissivity ratio for two-color type) by analog input or automatic emissivity computation function is selectable (option).
  • Conforming to CE marking
