Features

IR-FA series is an optical fiber transmission type radiation thermometer. Measurement light (radiant energy) captured by a size of a pinky, small lens assembly is led to a detecting element stored in a small box type thermometer. With small lens assembly and flexible optical fiber transmission, this thermometer is useful for measurements of a place where direct view is impossible or a narrow place, and a place where inductive interference occurs electrically.

  • Optical fiber can be used without cooling up to 150°C.
  • Optical fiber does not have electrical conduction so it is applicable for induction heating and explosion proof atmosphere.
  • Laser targeting option is available for checking measuring point.
  • Thermometer is compact, light weight, and DIN rail installation available.
  • For low temperature, for medium to high temperature, and two-color type etc. various types are available.
