MRU OptiMax Biogas Portable Gas Analyzer
The MRU OptiMax Biogas is a powerful portable biogas analyzer for landfills, anaerobic digesters, and RNG applications. The OptiMax Biogas Landfill Analyzer measures methane (CH4), hydrogen sulfide (H2S), carbon dioxide (CO2), and oxygen (O2), plus temperature and differential pressure. The OptiMax can be additionally outfitted with emission sensors of CO, NO, NO2, and SO2 making it a dual-purpose biogas and emissions analyzer all in one compact package. The MRU OptiMax Biogas Analyzer comes in pre-configured kits for landfills, biogas, and biogas/engine exhaust. The different kit options are listed below.
