Main Features
Hot-wet method with full heating design for the filter element and gas cell. The flue gas is extracted from the duct and passes through multi-stage filtration before entering the optical detection gas cell. The entire gas path is heated to high temperature, allowing complete vaporization of moisture and preventing interference caused by moisture adsorption of gases;
Integrated structural design of the entire unit eliminates the need for complicated tube connections and wiring, offering true portability and practicality;
Double-layer probe tube with vacuum design prevents high-temperature burns while isolating the influence of high-temperature duct heat on the gas cell, keeping the gas cell at a constant temperature for more accurate measurement results;
The gas cell, optical fiber, and spectral analysis components employ multiple cushioning and shock-absorption technologies, enhancing the reliability and stability of the instrument;
Large-area, high-porosity microporous filter element design effectively prevents lens contamination and greatly extends the instrument maintenance interval;
Remote real-time monitoring of the instrument's operating status via the internet enables full-process supervision of operational status and safety, standardizing quality control management;
Large touchscreen color display with a clean and intuitive user interface;
Replaceable rechargeable lithium battery provides long standby time, and continuous sampling for one minute after power failure thoroughly purges the gas cell;
Complies with new quality control requirements.
