GA-370 provides constant, ultrahigh-sensitivity and high-precision monitoring of trace impurities (CO, CO2 and CH4) for quality control at gas manufacturing facilities. This unit have features include cross-flow modulation dual-beam non-dispersive infrared (NDIR) analyzer provides continuous and stable zero drift-free measurements. Also, it has a minimum detection limit (MDL) of 10ppb which can support applications where high accuracy measurements are required. GA-370 has application for test gas generation in research and testing laboratories and for low concentration gas monitoring in coal and consumable fuels
