CHAMBER FOR NOX GAS ANALYZER

摘要

The present invention relates to an apparatus for measuring nitrogen oxides to measure nitrogen oxides (NOx) concentration of a predetermined air space and a variation thereof. More specifically, a chamber for measuring nitrogen oxides detects light, which is generated by a reaction of ozone (O3) and nitrogen dioxide (NO) in a predetermined high concentration using chemiluminescence, using the curvature chamber without light loss so as to be capable of precisely measuring the nitrogen oxides.
