Infrared thermometer for human body temperature measurement

Infrared thermometers generally measure the temperature of the skin on the surface of the human body, not the actual temperature of the human body; after a large number of clinical trials, we have found the relationship between the temperature of the forehead, the ambient temperature and the actual temperature of the human body, and carried out in the software With compensation correction, it can be said that the infrared human body surface temperature rapid screening instrument is a legal non-contact body temperature detection instrument. During SARS, a large number of applications in border inspections, checkpoints, airports, stations, docks and other occasions have a great effect on the temperature screening of large mobile personnel.
Comparison table of human forehead skin surface temperature and actual body temperature (data in this table is for reference only):

Forehead temperature 34 â„ƒ 35 â„ƒ 35.6 â„ƒ 35.8 â„ƒ 36 â„ƒ 36.2 â„ƒ 36.4 â„ƒ 37 â„ƒ
Actual temperature 36.2 â„ƒ 37 â„ƒ 37.5 â„ƒ 37.7 â„ƒ 37.8 â„ƒ 38.0 â„ƒ 38.1 â„ƒ 38.5 â„ƒ

The optical resolution is determined by the ratio of D and S, which is the ratio of the distance D between the thermometer and the target and the measurement spot diameter S. If the thermometer must be installed away from the target due to environmental conditions, but to measure a small target, you should choose a thermometer with high optical resolution. The higher the optical resolution, the higher the D: S ratio, the higher the cost of the thermometer.
According to needs and requirements, each door can enter 3000 people for effective measurement within 15 minutes. LH-SB-101 should be used. According to the function of the screening instrument, in one minute, each person can measure 40 people in theory, but in actual In operation, it is generally about 20 people. It can measure 300 people in 15 minutes. To detect 3000 people, 10 units are needed. In addition, the doorman should be equipped with a handheld Infrared Thermometer and a glass thermometer at the time of contact; preliminary suspicious high temperature is detected in the door type Personnel, and further verification.
The door type can measure the distance of 3-4 meters, and the handheld type is within 1 meter.
