Infrared thermometers have come in handy during the epidemic. In and out of communities, shopping malls, office buildings, major stations, vegetable markets, there are special people to lift a gun type of thermometer, empty operation against the forehead, this instrument is also known as the "forehead temperature gun".
Why use an forehead gun?
The forehead temperature gun measures the body temperature by absorbing and judging the infrared energy emitted by the human body. The forehead temperature gun can avoid cross infection and measure the temperature quickly. Therefore, it is especially suitable for screening people with fever in places with large flow of people, safe and fast.
How to use the forehead gun correctly
1. The normal range of human body temperature is "36℃~37℃". If the measured result exceeds 37.2℃, it will be preliminarily judged as fever.
2. Before measurement, the subject should wipe off the sweat and sebum, keep the forehead clean and dry, and the hair should not cover the forehead.
3. If the temperature difference between the two environments is too large, the subject should take a rest in the measuring environment for about 15 minutes. The measurement can be made more accurate after the temperature is adjusted to the environment.
4. During measurement, the nozzle of the forehead thermometer should be aligned with the center of the measured forehead, and the position between the two eyes should be slightly up, no more than 1cm from the forehead.
How does the wing gun work? Is it harmful to the human body?
1, the forehead temperature gun, also known as the infrared thermometer, absorb the infrared radiation energy emitted by the human body to determine the body temperature.
2. Any object above absolute zero (-273℃) will send out infrared ray, forehead temperature gun through the sensor to receive infrared ray, get the induced temperature data.
3. Since a forehead thermometer measures temperature by absorbing energy, it is not harmful to the human body when it is taken.
The human body sends out the infrared ray energy, the forehead temperature gun tests the body temperature by collecting the infrared radiation energy. Since infrared radiation is received passively, not emitted, there is no radiation to the human body. As a result of the environmental temperature, the movement of the person itself, the forehead temperature gun data can only be used as a reference, if the feeling of fever, had better use more accurate mercury thermometer or electronic thermometer, more accurate results.
