Main functions

1. The nCLD AL3 is a high-precision nitrogen oxides analyzer based on chemiluminescence detection (CLD) technology. This three-channel environmental air monitoring instrument features modular design capable of simultaneous measurement of NO, NO₂, NOx, and NH₃ concentrations;

2. With real-time discrimination capability for NO, NO₂ and NOx species, the analyzer delivers ultra-high sensitivity at ppb to ppt levels, making it ideal for background atmospheric studies, urban pollution monitoring, and laboratory simulation research
