General technical conditions for human body rapid thermometer
Infrared human thermometer is a non conventional device used for specific purposes, mainly to quickly detect individuals with a fever exceeding 38 ℃ (or a specific temperature) in a large number of abortions. It is a typical "screening" device. This instrument has been widely used in various public places and has played a significant role in screening SARS patients and controlling the spread of the disease.
At present, the sensors used in infrared screening equipment on the market have a wide measurement range, and the wider the measurement range, the greater the error in a specific temperature range. In addition, there are still issues with high measurement uncertainty within the full range of this type of instrument, as well as differences in deviation when measuring the same temperature with different instruments of the same batch and model under the same conditions. Without standards, the quality of products is unstable. Therefore, the National Standards Committee organized relevant departments to urgently launch the development of the national standard "General Technical Conditions for Infrared Human Surface Temperature Rapid Screening Instrument" on May 9th.
General technical specifications for rapid human thermometer
Experts point out that due to the significant differences in the working environment conditions of non-contact infrared rapid screening devices for human surface temperature, the thermal radiation rates of the working objects vary greatly, making it difficult to limit specific temperature values, correction values, and measurement distances in standards. When using this standard, enterprises not only need to strictly comply with the provisions of the standard, but also need to conduct a lot of experimental work in the above aspects to determine the measurement distance, specific temperature values, and correction values of the instrument, and clearly indicate them in the product manual or other documents according to the standard requirements.
The main purpose of a human thermometer is to detect the temperature of the human body in public places such as entry and exit ports, airports, stations, docks, hospitals, offices, factories, schools, hotels, and office buildings. It is convenient for screening patients with fever symptoms to reduce transmission and the spread of the epidemic.
