We got feedback from the staff who actually operated the temperature gun in the residential property of several companies. Although the body temperature gun is convenient and quick, it can quickly display the body temperature of the subject as long as it is aimed at the forehead of the human body, but the measurement result of the body temperature gun is easily affected by the external temperature.

When the gun body temperature is low, or the body surface temperature is too high or too low, it is easy to cause inaccurate or unmeasurable body temperature. On the other hand, when the temperature gun is low, the temperature measurement will be inaccurate. Many people often use it directly after getting it to temperature measuring gun, without receiving specific training, and sometimes the temperature measurement is inaccurate due to improper use.
