IR-FASNNU (400 to 900 C)

Infrared Thermometer (Fiber Type)

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.
