SGEP-300NH3

Based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology, the ammonia absorption spectral line at 1512nm was scanned and analyzed, and the ultra-low concentration of ammonia was measured using digital phase-locked amplifier and long-path gas chamber and other advanced technologies. The removable or in-situ installation method can be flexibly selected according to the requirements of the test conditions. The field installation is flexible and the maintenance is simple, which can meet the requirements for the detection of injected ammonia or escaped ammonia in the SCR/SNCR unloading process.
