The infrared thermometer is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output, etc. The optical system gathers the infrared radiation energy of the target in its field of view. The size of the field of view is determined by the optical components of the thermometer and their positions. The infrared energy is focused on the photodetector and converted into corresponding electrical signals. This signal is converted into the temperature value of the measured target after being corrected by the amplifier and signal processing circuit according to the internal treatment algorithm of the instrument and the target emissivity.
The infrared thermometer used to measure human body temperature is called human body infrared thermometer. However, it must be clarified that there is no special medical or industrial infrared thermometer, because the manufacturing principle of infrared thermometer is the same. There are only infrared thermometers with high accuracy, high distance coefficient ratio and high performance, and infrared thermometers with low accuracy, low distance coefficient ratio and low performance. As long as the emissivity of the infrared thermometer is set to 0.95 (the emissivity of human skin is generally this value, and even if there is a difference, the impact is only within 0.3 degrees), it is in line with the requirements of human body temperature measurement. (For example, all brands of cars can run at a speed of 40 yards, and high-end cars can run at a speed of 200 yards. However, there is no difference between a car that runs at 40 yards and a car that runs at 200 yards, only the difference between a car with high performance and a car with low performance.).
The principle of the infrared thermometer is to convert the radiant energy of the infrared ray emitted by the measured object into an electrical signal. The size of the infrared radiation energy is related to the temperature of the object itself. The temperature of the object can be determined according to the size of the converted electrical signal. All objects above absolute zero will radiate infrared ray by themselves. The function of infrared thermometer is to collect the infrared ray emitted by objects, and it will not emit any harmful radiation at all, so it is completely harmless to human body.
1. Non contact, do not touch the other party when measuring human temperature, avoid infection risk, and ensure safety
2. Fast temperature measurement, accurate reading, suitable for rapid screening of large numbers of people
3. It is not necessary to enter the other side's ear canal or replace the earmuff when measuring the body temperature. It is clean and sanitary
4. Laser positioning can accurately measure the temperature of the target part, and can measure the temperature of forehead, armpit, body surface, etc
5. The temperature limit can be set. When the temperature exceeds the limit, an audible alarm will be given to accurately check the abnormal temperature in the crowd
6. Infrared temperature measurement is harmless to human body.
