Since the outbreak, temperature measurement has become an indispensable link before entering various residential areas, office buildings and public places with more personnel. However, in the actual temperature measurement process, the temperature measured by some outdoor temperature measurement points tends to be out of place with several degrees lower than the normal body temperature. What caused this situation? How should the temperature measuring gun be used in daily protection?

At present, the commonly used electronic temperature gun is called the frontal temperature gun, also known as an infrared thermometer, which measures body temperature by absorbing the infrared radiation energy emitted by the human body. "Compared with mercury thermometers and ear thermometers, the forehead temperature gun has the advantage of effectively avoiding contact and has a faster temperature measurement. It is suitable for screening people with fever symptoms in places with large flow of people." The normal operating environment should be 16 ℃ to 35 ℃ indoors, so when used outdoors, the weather is too cold or too hot or even the testee has just come out of the car with a long period of warm air, it will affect the temperature measurement.

Non-Contact Infrared Thermometer

When the temperature measurement environment is not ideal and it is difficult to calibrate with mercury thermometers and other measuring instruments,  the following two methods can be adopted:

One is to first measure a reference temperature with the unheated people, and use it as a reference. Once there is a significantly higher temperature than the reference temperature, the second measurement is performed immediately.

The second is to use a warm baby whose temperature is not too high and stick it on the outside of the temperature measuring gun to help it maintain the normal working temperature.

Community temperature measurement is generally an outdoor environment. At present, the weather is cold. It is normal for the temperature gun to have such an error. Therefore, in an outdoor environment, it is recommended to change the temperature gun from the forehead temperature measurement mode to the body surface temperature measurement mode. To measure the temperature of your wrist, just lift the sleeve slightly and measure the surface of the skin that was just covered by clothing. "Be careful of the distance when measuring temperature." If the measured body temperature is still too high in such a case, you don't need to panic. Instead, you can use a physical thermometer to accurately measure and determine whether the person actually has a temperature abnormality.

Everyone should treat the matter of using the temperature gun to measure the temperature in the community as normal. Under normal circumstances, the temperature screening efficiency of the temperature gun can be guaranteed, and it should be coordinated during special periods. This is an effective guarantee for the community residents during the epidemic, but at the same time, it does not need to follow the trend. Universal use does not mean that it is the most Yes, the most common physical thermometer is still recommended for home temperature measurement. It has higher accuracy, is used in non-public places, and is convenient for self-sterilization.
