LGR’s O2/CO2 Analyzer is the first instrument

capable of reporting oxygen, carbon dioxide and

water vapor in air with extremely high precision

and fast response. Designed for measurements

in ambient air for applications requiring high

precision, the O2/CO2 Analyzer applies LGR’s

proven cavity enhanced laser absorption

spectroscopy technique for simultaneous

continuous measurements of these three

important atmospheric gases.

The O2/CO2 Analyzer is simple to use, low power

and rugged which makes it ideal for field studies.

The ability to measure O2and CO2 at the same

time simplifies the analysis of air samples. 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 CO2

and O2 on a dry mole fraction basis directly

without drying or post processing. Furthermore,

LGR’s new “Extended Range” option provides

accurate CO2 measurements up to 10% mole

fraction without reducing precision and sensitivity

at typical ambient levels - a unique LGR capability.
