Clinical ear thermometer sensing infrared thermal radiation from an eardrum is capable of measuring temperature in less than a few seconds and has rapidly become widely used. To meet the demand of calibration and conformity assessment in industry, AIST has developed a standard blackbody system traceable to the International Temperature Scale (ITS-90) for the calibration of the clinical ear thermometers. An expanded uncertainty of around 30 mK has been evaluated in the temperature range from 35 ºC to 42 ºC. The AIST has also established a high-quality traceability system for industries.
