Industrial temperature guns can be used to measure body temperature, but the accuracy is not too high. Since the industrial temperature gun uses infrared thermometer, it reflects the internal temperature by measuring the temperature of the surface of the object. However, there is a certain error between the temperature on the surface of the object and the internal temperature, and the difference level between the surface temperature and the internal temperature of the object is usually around 1℃, so the accuracy of the infrared thermometer is not as accurate as that of the mercury or electronic thermometer. If the patient is measured 38 ℃, will be subtracted from this temperature 1 ℃ to be the real body temperature. Therefore, the industrial thermometer gun to be higher than the mercury or electronic thermometer, measuring the temperature of 1 ℃, if you want to get the accurate temperature will be subtracted from this temperature 1 ℃ on it.
