IR-FA SERIESFIBER OPTIC RADIATION THERMOMETERThe IR-FA series is a fiber optic radiation
thermometer featuring multi-function and highspeed response.
Three types, single-color type for low temperature,single-color type for medium/high temperature andtwo-color type, are available.
IR-FA series realized usability and stabletemperature measuring as digital temperature
display and parameter setting functions, signal
modulation and optional analog output are built in.
Various options including lens assembly withfinder, laser-spotting function, communications
interface and analog input which enables
emissivity external settings or automatic
emissivity computation are available.

IR-FAS,-FAQH■ FEATURES● Low temperature type with high-speed response(20ms) and short wavelength enables to measureobjects with low emissivity like as metals.
● Medium/high temperature type with high accuracy( ± 0.5 to 1% for 1000 to 2000℃) 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.
● Temperature measuring of high speed movement
material, inductive heating object, explosion-proof
environment and vacuum equipment are applicable.

IR-FACR■ STRUCTURE● Digital temperature display and parameter setting with
key operation.
● Compact, light weight and DIN rail mounting.
● By using heat-resistive fiber optic, measuring in theenvironment at 150℃ is possible without any watercooling.
● Stable temperature measuring is possible by signal
modulation function.
● Laser function for easy spotting of measuring point(option).
● A lens assembly with finder for spotting of measuring
point with eyes is available from accessories.
● Communications interface (RS485) enables data logging and parameter setting on a computer.
● Emissivity setting (emissivity ratio for two-color type)by analog input or automatic emissivity computation
function is selectable. (option)● CE conformed.
