About infrared thermometers
Now, infrared thermometers are widely used, what is the measurement accuracy of this device? What is the error? What are the factors that affect its measurement accuracy? In fact, there needs to be a clear explanation. Generally speaking, the measurement accuracy of this kind of equipment is not high. When measuring human body temperature, the error is about 1 to 2 °C. If there is a heat source nearby, the temperature measurement will be affected. Considering the large flow of people, contact thermometers cannot be used, and this measuring device is used in this way. However, if the body temperature is too high, it is necessary to use a contact thermometer for several re-examinations. In fact, measuring body temperature does not completely determine whether it is new coronary pneumonia, and a common cold and fever can also cause body temperature to rise.
