Calibration Method of Clinical Type Infrared Thermometers and Estimation Uncertainty in Different Blackbody Cavities

Abstract

Abstract In recent years, radiation thermometers or infrared thermometers are frequently preferred in many different sectors from the health sector to the iron and steel industry, food, agriculture, chemistry and automotive, due to their fast measurement capabilities, reasonable prices, wide measurement ranges and practical use. In this study, the calibration systems of infrared clinical radiation thermometers, which are widely used in our hospitals and homes and become more important with the sudden expansion of their usage areas (closed areas, meeting rooms, shopping malls, schools and offices), especially during the Covid-19 period, were investigated. The measurement of human body temperature is an important physiological measurement used primarily for diagnosis, surgery, especially during pandemic diseases such as covid-19, intensive care and treatment procedures. Different types of clinical thermometers are used in body temperature measurement and we can examine these thermometers in two groups: contact thermometers and non-contact thermometers. To have confidence in the accuracy of the measurements of the temperature measuring device, clinical thermometers, it is important that the device is calibrated traceable to the 1990 International Temperature Scale (ITS-90).
