Since the outbreak of the epidemic, large supermarkets, park attractions and other public places, often see infrared automatic thermometer, from the beginning of the curiosity to take it for granted, infrared thermometer has become a part of our daily life.
Many people are curious, how can the infrared automatic thermometer measure the body temperature without contact and ensure the accuracy rate? First of all, the distance requirements of different infrared automatic thermometers are not the same, and the distance required by more Ryuke is 3-10cm, and the measurement accuracy is ±0.2 °C.
As for the principle of the infrared automatic thermometer, in simple terms: when the infrared thermal radiation of the human body is focused on the detector, the detector converts the radiated power into an electrical signal, which is displayed in temperature units after the ambient temperature is compensated.
With the continuous advancement of technology, the infrared automatic thermometer in the detection of body temperature abnormalities, in the form of only a digital reminder, but added an indicator light reminder, in the temperature abnormality, orange or red indicator light flashed, to help quickly distinguish high body temperature.
When setting the infrared automatic thermometer, first of all, to determine the location, must be set at the entrance of people' must pass, the installation method is currently mostly wall mounted, vertical two, and these two installation methods have achieved convenient and fast movement. In addition, when you start using, you only need to set the language and mode to use.
At present, the epidemic has not completely passed, and we still need to be rigorous. The emergence of infrared automatic thermometers provides great support for epidemic prevention work, saves manpower, and makes temperature measurement work more simplified and convenient for our lives.
