Product Description

1.About NDIR CO2 sensor：

    Our NDIR CO2 sensor has a simple configuration with its infrared radiation source, cell, optical filter and infrared detection part.

    The optical filter to detect infrared is composed for 2 kinds of infrared wavelength. One is the wavelength band which is well absorbed by CO2, and the other is the wavelength band which is less affected by CO2 or other gas components.

    As it measures the ratio of infrared absorption amount itself, our NDIR CO2 sensor realizes stable measurement performance while compensating the influence of degradation of radiation source etc.
