Working principle

The mechanism of 7515 CO2 is that CO2 has a certain absorption effect on infrared radiation. The CO2 probe of 7515 contains an infrared emission source and an infrared detector. Due to the absorption effect of the measured CO2, the intensity of the infrared light measured by the infrared detector will change, which has a certain linear relationship with the concentration of CO2. Therefore, the corresponding concentration of CO2 can be calculated based on the measured infrared light intensity
