Are Infrared Thermal Camera Accurate?

During the epidemic, people are most concerned about whether the body temperature is normal. However, in railway stations, subway stations, airports, shopping malls and other crowded places, the efficiency of using handheld thermometers for testing is very low. Now, many railway stations, subway stations, airports, hospitals, government agencies, shopping malls,and office buildings have begun to use infrared An COVID-19 Non-contact Thermometer is used to conduct a preliminary inspection of the crowd. If the body temperature is abnormal, the device will automatically alarm, and the medical staff will go to carefully check it. The use of infrared imaging thermometers greatly improves the temperature measurement speed, and improves the efficiency of crowd travel while ensuring accuracy.

But whether the infrared imaging Thermal Camera is accurate in temperature measurement, can it accurately detect whether everyone has a high fever?

Body temperature screening is a means of screening and investigating suspicious cases in this epidemic. According to relevant information, it can be seen that infrared thermal imaging thermometers can achieve some comparisons with traditional thermometers or forehead thermometers and other measuring devices. Long-distance, such as several meters, can perform temperature detection on multiple targets at the same time without contact.

This can reduce the detention and personal contact caused by body temperature detection, which has certain advantages in reducing the risk of disease transmission, and is relatively safe and convenient. It is a way to identify feverish people in public places.

The infrared imaging Thermometer converts the invisible infrared energy emitted by the human body into a visible thermal image. In simple terms, it changes the temperature from one value to an image full of temperature data. High efficiency is one of its biggest advantages. one.

Generally, infrared thermometers measure the temperature of the scene in the scene as a hot spot; while the infrared imager records the relative value and distribution of the infrared radiation flux of the scene in the scene, and the resulting infrared image contrast; infrared imaging measurement The thermometer measures the temperature distribution of the infrared image of the scene object, and displays it in isotherm, false color, etc., so as to obtain an infrared image corresponding to the scene and containing the temperature and its distribution.
