Greenhouse Gas Analyzer (CH₄, CO₂, H₂O) Datasheet

LGR’s Greenhouse Gas Analyzer is the world’s most advanced instrument for simultaneous measurements of methane, carbon dioxide and water vapor. Quite simply, no other analyzer provides higher performance, ruggedness, reliability and ease of service.

The GGA is simple to use, low power and rugged which makes it ideal for field and air quality studies. The ability to measure all gases quickly makes the GGA an excellent choice for eddy covariance and chamber flux measurements. In addition, analysis of the measured absorption spectra allows the instrument to accurately correct for water vapor dilution and absorption line broadening effects and thus to report CH₄ and CO₂ on a dry mole fraction basis directly without drying or post processing. Furthermore, LGR’s new “Extended Range” option provides accurate methane measurements at levels up to 10% (without dilution) without reducing precision and sensitivity at typical ambient levels - a unique capability to LGR
