What are the advantages of using infrared thermometers to measure human body temperature
　　? Infrared thermometers used to test human body temperature are called human infrared thermometers. However, it must be clarified that there is no distinction between special medical or industrial infrared thermometers, because the manufacturing principles of infrared thermometers are the same. There are only high-precision, high-distance coefficient ratio, high-performance infrared thermometers and low-precision, low-distance coefficient ratio and low-performance infrared thermometers. As long as the emissivity of the infrared thermometer is set to 0.95 (the emissivity of human skin is generally this value, even if there is a difference, the impact is only within 0.3 degrees), it meets the requirements of human body temperature measurement. (For example: all brands of cars can run at a speed of 40 mph, and high-end cars may be able to reach a speed of 200 mph, but there is no distinction between cars that specialize in running at 40 mph and cars that specialize in running at 200 mph, only the difference between cars with high and low performance.)
　　Advantages of infrared thermometers for measuring human body temperature
　　1. Non-contact, no need to touch the other person when measuring human body temperature, eliminating the risk of infection and ensuring safety
　　2. Rapid temperature measurement and accurate readings, suitable for rapid screening of large numbers of people
　　3. No need to enter the other person's ear canal when measuring body temperature, no need to replace earmuffs, clean and hygienic
　　4. Laser positioning, accurate measurement of the temperature of the target part, can measure the temperature of the forehead, armpits, body surface, etc.
　　5. The temperature limit can be set, and an audible alarm will be issued when the limit temperature is exceeded, accurately screening people with abnormal body temperature in the crowd
　　6. Infrared thermometer, no harm to the human body
