In order to ensure the normal use of its temperature measurement, it is necessary to deploy and debug it reasonably. The relevant issues during installation and use are listed as follows:
1. Is the infrared thermal imaging temperature measurement gate guard suitable for outdoor installation?
In the application of human body temperature screening, try to avoid outdoor installation as much as possible; If it is necessary to install outdoors, a closed temperature measurement environment needs to be built, and transparent materials cannot be used. It is also not suitable to place the thermometer and temperature personnel in a convective environment. It is best to build an environment such as a canvas greenhouse to keep the entire greenhouse in a constant temperature state; Only in this way can the thermometer ensure relatively accurate temperature measurement when working outdoors.
2. Precautions for indoor installation.
When installing a thermometer indoors, it should be installed on the front of the temperature measuring personnel's entrance and exit channels; When deploying the detection channel, avoid direct sunlight, glass curtain walls, and positions facing the door. The temperature measurement channel can be set after entering the door, turning 90 degrees and deploying personnel to enter and exit the channel to reduce the impact of temperature differences inside and outside the door on temperature measurement accuracy; Also, it is important to avoid other scenes behind the temperature measuring channel and avoid heat sources such as ovens, air curtain outlets, and air conditioning vents to prevent false alarms.
3. The relationship between the distance between the person being measured and the thermometer, the installation distance, and the focal length of the thermometer lens.
In principle, temperature measurement is based on the heat radiated from human body temperature. Therefore, the closer the person being measured is to the thermometer, the higher the temperature measurement accuracy; Installation at different distances can be compensated for through corresponding temperature correction. The infrared thermal image used by the thermometer also determines the temperature measurement distance based on the focal length of the lens. The premise of temperature measurement is that the person being measured must be within the field of view of the thermal image; According to the usage scenario on site, a 9mm thermometer should be used within a range of 1-3 meters; 3-5 meters, it is recommended to use a 13mm thermometer; Within a range of 5-10 meters, it is advisable to use a 19mm thermometer.
