2. How to use infrared thermometer correctly? Body temperature screening is a method used in the screening and investigation of COVID-19 suspicious cases, and the handheld infrared thermometer should be operated strictly in accordance with the instructions to ensure the accuracy of the readings. It is normal that slight difference may exist in readings when measuring different parts of the body. The temperature in winter and spring is still relatively low, so the handheld infrared thermometer should be calibrated before use, especially when measuring people who enter room from the outside. It is recommended to measure the skin covered by clothing or scarves, such as wrist or neck, so that the figure will be more accurate when using infrared thermometer outdoors.

According to the principle of infrared thermometer, body temperature can be measured without touching the skin, so the probability of causing cross infection is extremely low since those who are to take or be taken temperature wear masks during measurement.
