Some knowledge points of infrared forehead temperature gun, infrared forehead temperature gun manufacturers tell you

Infrared frontal temperature gun manufacturers believe that the frontal temperature gun is a measuring instrument that uses infrared receiving principle to measure human body temperature. When in use, the human body temperature can be measured quickly and accurately by aligning the detection window with the forehead position.

Infrared forehead temperature gun manufacturers believe that the principle of forehead temperature gun:

(1) Any object will emit infrared rays above zero (-273). The size of the radiant energy and its distribution according to wavelength are closely related to its surface temperature. The forehead temperature gun receives infrared light through a sensor and obtains sensed temperature data. The infrared wavelength emitted by the human body at (36~37) is 9~13 meters

(2) The standard temperature of different temperature measurement positions is different.

(3) According to this principle, by detecting the surface temperature of the human forehead and correcting the temperature difference between the forehead and the actual body temperature, an accurate body temperature can be displayed. The middle part of the eye is a source of radiation close to normal body temperature compared to the body surface temperature. Place the forehead temperature gun at a distance of 5-6cm to measure the temperature. Accuracy is 0.3.

(4) The manufacturer of the infrared forehead temperature gun believes that the accuracy of the forehead temperature gun is not high, and the body surface temperature is greatly affected by the environment. Medical treatment is not recommended, but it can be used for rapid and non-contact safety investigation of influenza.

Some people have heard of infrared forehead thermometers, also called radiation thermometers, for fear that they will produce harmful radiation. This fear is superfluous. This radiation is referred to as infrared. As long as the temperature is higher than room temperature, infrared radiation will be produced, so the human body will also produce infrared radiation. The thermometer absorbs the infrared rays emitted by the human body to measure the temperature, and it does not produce radiation by itself. Therefore, the infrared thermometer is very safe.

Infrared frontal temperature gun manufacturers believe that infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long life, and is widely used in various occasions. The infrared thermometer is equipped with a laser sight, which helps to aim the target quickly. The main control MCU reads and processes the temperature data of the infrared thermometer chip through I2C communication, and then displays the temperature data on the LCD through SPI communication. It has the functions of working mode setting, buzzer alarm, temperature data storage, temperature data transmission to the upper computer for data analysis and so on.

Infrared forehead temperature gun manufacturers believe that because there is no need for direct contact with human body parts, and the measurement is accurate, effective, simple and fast, compared with infrared imaging thermometer, the use cost is very low, so the forehead temperature gun is widely used in human body temperature measurement. Especially in densely populated areas, through the comprehensive use of relevant personnel, the forehead thermometer and infrared imaging thermometer complement each other, providing more effective measurement and monitoring methods, and playing an indispensable role in protecting the safety of the people. effect. In many places, a few forehead thermometers are often enough to measure the temperature of the people in the area.
