This product employs a self-developed laser and photodetector, utilizing a high-performance microprocessor to achieve precise temperature control and concentration measurement. Combined with independently developed concentration inversion and temperature compensation algorithms, it enables accurate measurement of methane concentration. Based on Tunable Laser Gas Absorption Spectroscopy (TDLAS), this sensor features a stable and reliable optical structure, long absorption path, high detection sensitivity, ease of use, and reliable performance, making it a core sensor for combustible gas detection.
Strong anti-interference ability:Precision methane absorption spectroscopy detection, resistant to water vapor and interference gases;
Highly adaptable to the environment:Precise temperature control, concentration adaptive algorithm and temperature compensation, suitable for wide temperature range operating environments;
Low usage and maintenance costs:Optical non-destructive testing, high real-time performance, maintenance-free, and lifetime calibration-free.
