Laser Gas Analysis System

Classification：

eLAS Series

Product Description:

The eLAS series of laser ammonia analyzer is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology to scan and analyze the ammonia absorption spectrum line at 1512nm, and the digital phase-locked amplifier and long optical path gas chamber and other advanced technologies to achieve ultra-low concentration measurement of ammonia. The extraction method is selected according to the requirements of test conditions, which is simple to install and maintain, and can meet the requirements of injected or escaped ammonia detection in SCR/SNCR denitration process.
