This document highlights the safety-critical role of oxygen measurement in natural gas systems. Oxygen entering via compressors, VRUs, or pipeline leaks can combine with CO₂, H₂S, and moisture to form aggressive acids that damage carbon-steel infrastructure. Endress+Hauser’s quenched-fluorescence analyzers deliver rapid, highly accurate, low-maintenance O₂ detection—even in harsh, remote environments with high contaminant loads. Fast response helps identify leak sources early, reducing corrosion risk, false alarms, and operational hazards across the entire gas production and distribution network.
