High sensitivity, high selectivity, simple structure, strong anti-interference ability.

Unique optical path design: The design of isolating the main optical components from the high-temperature gas chamber avoids the influence of heat sources on the optical components, improves the stability of the optical path and the life of the optical components.

The suspended optical path design is adopted, and the optical path is shockproof to ensure the long-term stability of the optical path.

Zero gas spectrum fast subtraction technology: While ensuring the optical path, the gas chamber volume is reduced as much as possible to achieve rapid replacement of sample gas and zero gas, quickly obtain zero gas spectrum and subtract it in real time, reduce the influence of background noise and optical noise, and ensure the long-term stability and reliability of data.
