疫情防控中常用非接触红外体温计的使用指导分析

Analysis on the application guidance of generally noncontact infrared thermometer in preventing and controlling pandemic

目的:从计量学的角度对疫情中常用非接触红外体温计进行监管。方法:依据国家计量检定规程,分析非接触红外体温计测温的准确度影响因素中环境、发射率和距离系数,对使用非接触红外体温计给出正确指导,尤其是在低温环境。结果:非接触红外体温计适用于公众场所体温的初步测量,针对大型公共场所,红外人体表面温度快速筛检仪是首要选择。结论:非接触红外体温计在公众场所预防控制疫情扩散中起到重要作用。

Objective:To supervise the generally noncontact infrared thermometer in pandemic from the perspective of metrology.Methods:According to the national metrological verification regulations,the environment,emissivity and distance coefficient in the influence factors of accuracy of noncontact infrared thermometer were analyzed,and the correct instructions of using non-contact infrared thermometer were provided,especially at low-temperature environment.Results:The noncontact infrared thermometers were suitable for the preliminary measurement of body temperature in public places.For large-scale public places,the infrared human body surface temperature rapid screening instrument was the first choice.Conclusion:Noncontact infrared thermometer plays an important role in preventing and controlling the diffusion of the pandemic in public places.
