The SS2100a gas analyzer measures accurate trace gas components (H2O, CO2, H2S, NH3, and C2H2) in natural gas and hydrocarbon processing applications using tunable diode laser absorption spectroscopy (TDLAS) technology. It requires little maintenance and does not need recalibration or periodic replacement parts. The SS2100a is certified for ATEX Zone 2.
Gas analysis: ppb level measurement of H2O & NH3, ppm level measurement of H2O, H2S, CO2, NH3, and C2H2, and % level measurement of H2S and CO2
Natural gas: production, storage, transportation, distribution
