The structure and composition of this product: The product is composed of a shell, an infrared temperature sensor, a signal receiving processor, a key, a COB board, a and a crystal display of application: display the body temperature of the measured object by measuring the heat of the forehead
working principle:The infrared receiving principle is used to measure the body temperature of the human body. When in use, it is only necessary to conveniently align the detection window with the position of the forehead to quickly and accurately measure the body temperature.The principle of infrared forehead temperature gun-all objects with a temperature above zero (-273.15 ° C) are constantly emitting infrared energy into the surrounding space. Its characteristics, energy size, wavelength distribution, etc. are closely related to the surface temperature of the object. Therefore, by measuring the infrared energy radiated by the object itself, its surface temperature can be accurately determined. This is the principle of infrared temperature measurement.
- 1. The non-contact human body infrared thermometer is designed for measuring a person’s body temperature, and the room temperature does not affect the measurement.
- 2. According to different skin types and thickness, there may be temperature difference.
- 3. When the indoor temperature is obviously different, the infrared thermometer should be placed in the room for 15-20 minutes in advance.
