Many types of thermometers have been developed to measure body temperature. Infrared thermometers (IRT) are fast, convenient and ease to use. Two types of infrared thermometers are uses to measure body temperature: tympanic and forehead. With the spread of COVID-19 coronavirus, forehead temperature measurement is used widely to screen people for the illness. The performance of this type of device and the criteria for screening are worth studying. This study evaluated the performance of two types of tympanic infrared thermometers and an industrial infrared thermometer. The results showed that these infrared thermometers provide good precision. A fixed offset between tympanic and forehead temperature were found. The measurement values for wrist temperature show significant offsets with the tympanic temperature and cannot be used to screen fevers. The standard operating procedure (SOP) for the measurement of body temperature using an infrared thermometer was proposed. The suggestion threshold for the forehead temperature is 36 °C for screening of fever. The body temperature of a person who is possibly ill is then measured using a tympanic infrared thermometer for the purpose of a double check.
已经开发出许多类型的温度计来测量体温。红外体温计 (IRT) 快速、方便且易于使用。有两种类型的红外体温计用于测量体温：鼓膜和额头。随着 COVID-19 冠状病毒的传播，额温测量被广泛用于对人群进行疾病筛查。有必要研究这种类型设备的性能和筛选标准。本研究评估了两种类型的鼓膜红外体温计和一种工业用红外体温计的性能。结果表明，这些红外体温计具有良好的精度。发现鼓膜温度和额头温度之间存在固定的偏移。腕部温度的测量值与鼓膜温度存在显著偏移，不能用于筛查发热。提出了使用红外体温计测量体温的标准操作程序 (SOP)。建议将额温筛查发热的标准定为 36°C。对于可能患病的人，然后使用鼓膜红外体温计进行体温测量，以进行双重检查。
