Blackbody Furnace for Ear Thermometer IR-RE01


This equipment is the calibration equipment for calibrating ear thermometer.
It was developed under the guidance of The National Institute of Advanced Industrial Science and Technology(AIST).
It is a bath type blackbody furnace with cave radiation tube.
High precision calibration is possible because of use of cave radiation configuration specific to ear thermometer and bath that is excellent in temperature stability and distribution because it uses water as thermal medium.
In the blackbody cavity reference temperature measurement, scale calibrated 4 wire platinum RTD is used.
This equipment can provide the calibration of National Institute of Advanced Industrial Science and Technology. (Option)
