After release of medicines, disinfectants, thermometers and other items are in short supply. Some people want to use industrial infrared thermometers for emergencies when they cannot afford medical infrared thermometers. So can industrial infrared thermometers measure human body temperature?
First, let's talk about difference between industrial infrared thermometers and medical infrared thermometers.
Whether industrial grade or medical grade, their principle is same and value of surface temperature of object is measured.
Medical thermometers are intended only for measuring human body temperature. Ordinary medical thermometers cannot adjust emissivity. The general operating temperature is room temperature, and measurement function cannot be realized under low temperature conditions. The measurement range is from 36°C to 37°C of human body temperature, and medical temperature gun has good measurement accuracy in this measurement range.
The industrial temperature gun has a wide range of applications and good adaptability to ambient temperature. The general working temperature is -20°C to 50°C or even higher. The measurement range is from minus thirty to forty degrees to several hundred degrees above zero. The emissivity can be adjusted, it has good measurement stability at extreme temperatures and high reproducibility.
Looking at it this way, there is no problem with measuring human body temperature with an industrial infrared thermometer, but it is not recommended to use it this way because it is not very accurate. The temperature of forehead is 1-2 degrees lower than actual body temperature, and temperature of forehead is strongly influenced by environment.
The medical thermometer difference has been corrected by software before leaving factory. Those below 36°C will display 36°C, and temperature compensation has been performed for other measurement intervals. However, industrial thermometers reflect real skin surface temperatures without algorithmic compensation, so you will see many measured temperatures below normal body temperature.
If you really don't have a thermometer at home, you can also use one in an emergency. But you should know that this data is for reference only, not that accurate.
