MGL Series – NDIR is a infrared analyzer can be used for measurement of the concentration of gases in sample gases simultaneously. It is based on the single source two beams non dispersion infrared (NDIR) method been used for this analyzer by Micro-Flow NDIR technology. NDIR Analyzer is  designed with 4U rack mountable and wall mount smaller physical dimensions and the simple digital pulsable infrared source and two beam systems. The general application is emission flue gas, landfill, anaerobic digestion and other fermentation processes.
