There are two types of non-contact infrared pyrometers for industrial use and medical use. Medical infrared thermometers, infrared ear thermometers and infrared body surface temperature detectors should be preferred for measuring human body temperature because of their narrow measurement range, high resolution, and small error. On the contrary, the industrial infrared pyrometer has a wide measurement range, low resolution and large errors. However, at present, many SARS prevention checkpoints still use industrial infrared thermometers to measure human body temperature. Therefore, it can only serve as a preliminary screening. For suspected fever objects, medical thermometers must be used to determine and eliminate them.

Now, many infrared pyrometers have large errors. According to relevant personnel, the existing various infrared pyrometers are modified from industrial thermometers, which can only measure the temperature of the forehead surface, not the underarm temperature. The surface temperature of the forehead is not only lower than the temperature of the armpit, but is also greatly affected by the ambient temperature, resulting in large measurement errors in the existing various infrared pyrometers. Infrared temperature measurement products with environmental temperature compensation function should be developed, which can accurately convert the underarm temperature according to the forehead temperature of the human body and the environmental temperature.

According to infrared pyrometer manufacturers, for the purpose of focusing on social interests and gathering more resources and forces to fight SARS, the new infrared thermometer can greatly reduce the technology and manufacturing threshold of infrared temperature measurement equipment, and also solve the domestic The core components of infrared temperature measurement are totally dependent on imports, shortage of supply, and high prices.
