Temperature gun to forehead or wrist? Which is more accurate?

Recently, due to the severity of the epidemic, people are not only restricted from going out, even if they can go out, they have to take temperature measurements everywhere, which is very inconvenient. At the moment, the most commonly used thermometer in public places is a temperature gun, which tells a person's temperature by holding it to his or her forehead or wrist and "di" it. But many people, after many trips, have found that many thermometers measure the temperature of their wrists as well as their foreheads, which raises the question of whether a thermometer gun is more accurate.

 

In fact, the temperature measuring principle of temperature gun is to quickly detect the temperature of corresponding position according to the infrared energy received. Almost all objects emit infrared light, and the amount of energy it contains is directly related to the temperature of the object. Of course, forehead and wrist are no exception. Therefore, the temperature gun that does not need to contact with the subject becomes the best temperature measuring instrument in public places.

 

Which is more accurate, the forehead or the wrist?

 

At the epidemic prevention and control sites, staff members usually point thermos guns at people's foreheads and wrists to measure the temperature. Which position is closest to the human body temperature? In the case of low outdoor temperature, the forehead and wrist are exposed for a long time with low temperature, and the measured temperature is generally lower than the normal body temperature. Therefore, it is more accurate to measure the part covered by clothes between the wrist and the arm.

 

It should be noted that although temperature gun can only let us know our general temperature status when we are out, it is best to use mercury thermometer or electronic thermometer to test at home to get more accurate results. If the temperature is higher than normal, we need to go to the fever clinic of the hospital in time. But even their own body temperature in the normal range and don't take lightly, because the fever is not patient COVID - 19 or other infectious diseases will appear symptoms, so we still need to wash your hands frequently in our daily life, often ventilated take a breath and make the corresponding disinfection measures, reduce the chance of infected themselves and their families as soon as possible.
