CO Analyzers

CO Analyzers

Designed for many demanding applications including eddy-correlation flux measurements, chamber flux measurements, combustion diagnostics, and trace-gas monitoring, these Analyzers have been applied successfully on-board NASA DC-8 aircraft for trace-gas measurements in the upper troposphere / lower stratosphere. In fact, the High-Sensitivity CO Analyzer and the High-Sensitivity N2O Analyzer are ideal for measuring carbon monoxide and nitrous oxide, respectively, in ambient air with data rates of up to 20 Hz, less than 1% uncertainty (without calibration; much higher accuracy may be obtained with calibration), and better than 0.1% repeatability. Neither analyzer is affected by other atmospheric gases or changes in ambient atmospheric pressure.
