The HGA-331 High-Precision Greenhouse Gas Analyzer employs Cavity Ring-Down Spectroscopy (CRDS) technology to simultaneously measure the concentrations of CO2, CH4, and H2O gases. With its unique internal temperature and pressure control algorithms, the analyzer delivers exceptional accuracy, precision, and low drift performance, providing measurements of unrivaled stability. Its measurement performance meets WMO standards, achieving a sensitivity of one part per billion (ppb), equivalent to the detection of one part in a billion.
