    Thermometer category

    The thermometer is a temperature measuring device that measures the temperature of the human body. There are various types. The temperature can be measured by the principle of thermal expansion and contraction of mercury or other liquids. Usually the main parts to measure body temperature are forehead, cochlea, mouth, armpits and anus. Medical thermometer products include traditional mercury thermometers, electronic thermometers, forehead guns and other products.

    Mercury thermometers are the most stable, with small deviations in measurement, but mercury thermometers display small numbers and have long measurement times, making it difficult for the elderly and emotionally unstable people to use them.

    The medical electronic thermometer can quickly measure the body temperature and directly display the value. It is suitable for human oral cavity temperature measurement, and can be used for first aid, screening or household use. Electronic thermometers do not contain mercury and are safer to use, combined with electronic screens can repeatedly display measurement results.

    The frontal temperature gun is also called infrared thermometer, which can accurately measure the temperature of the human body within 1 second. When in use, just point the probe to the forehead and press the button. The working principle is actually very simple: when the temperature of the object is higher than "absolute zero", that is -273 ℃, the object will radiate infrared rays outward. Using infrared probes to obtain the infrared light intensity of different objects, the temperature data can be displayed on the liquid crystal display through the amplification circuit and the analog-to-digital conversion circuit.
