Medical temperature measuring guns are used in areas where infectious diseases occur. They use far-infrared light to emit light signals to measure the temperature of the human body without touching the human body. It has special uses during the SARS and avian flu periods. The temperature is designed to be -50 to 480 ° C, and low-temperature measurement of minus 50 degrees is easily achieved, and it can also be used normally in low-temperature areas such as northeast and northwest.
All objects in nature that are above absolute zero (-273.15 ℃) are constantly radiating energy. The amount of radiant energy of an object and its distribution according to wavelength are very closely related to its surface temperature. The higher the temperature, the stronger the ability to emit infrared radiation.
