The Influence of High Temperature Weather on Human Body Temperature Measurement by Infrared Thermal Imaging Thermometer

Abstract

Infrared thermography thermometer is a non-contact temperature measuring equipment, which is widely used in the stage of large-scale epidemic of the covid-19 pandemic. It is used for rapid screening of human body temperature in crowded places at the entrance and exit of airports, docks, shopping malls, stations and schools. But when the outdoor temperature approaches or exceeds the body temperature in summer, can this method of measuring body surface temperature by infrared thermal imager be used as a standard for screening fever? Under the condition of high temperature in summer, the field experiment of measuring body temperature by infrared thermal imager is carried out, the experimental results are analyzed. We recommend the use of relative temperature difference for screening patients with fever.

“…Weather-related factors such as temperature, relative humidity, and wind velocity have also been found to be significantly correlated with patient body temperature, with effects varying in magnitude depending on the distances from outside to the measurement site (Spindel et al, 2021). For example, high environmental temperatures (above 99.5 °F) readily affect shell (skin) temperature and infrared thermometry measurements (Mei et al, 2021). Another study found that skin temperature was significantly affected by ambient temperature in both hot and cold conditions (Strigo et al, 2000).…”

Measurement and Processing of Thermographic Data of Passing Persons for Epidemiological Purposes

“…The experiments in simulated/actual environmental conditions in [ 9 ] proved that there must be an acclimatization period ranging from 2 to 9 min depending on the outdoor temperature before temperature screening. The use of relative temperature difference for screening patients with fever is recommended in [ 10 ] in the case of ambient temperatures higher than 37.5 °C.…”
