Principle

Infrared measurement technology:

Polar gas molecules absorb specific wavelengths of infrared light and have unique spectral absorption characteristics. The infrared light emitted from the infrared light source is modulated and passed through the non-absorbing reference chamber and the absorbed sample chamber respectively, and reaches the detector. The concentration of the measured gas is obtained according to the difference of different energy signals received by the detector. High measurement accuracy, good stability, fast response, low background gas interference.
