Zetian - Model OGA-100 -Odor Gas Analyzer
The OGA-100 Odor Gas Analyzer is an independently developed gas analysis product designed for online monitoring of odor gases from unorganized emission sources and main discharge outlets. Based on characteristic absorption spectroscopy and the PLS algorithm, it can simultaneously monitor various odor gases, including methyl mercaptan (CH4S), dimethyl sulfide (C2H6S), dimethyl disulfide (C2H6S2), styrene (C8H8), carbon disulfide (CS2), hydrogen sulfide (H2S), ammonia (NH3), trimethylamine (C3H9N), TVOC, and odor concentration (OU value). Additionally, other components such as SO2, NO, and NO2 can be included according to user requirements.
