Dynamic chambers used for measuring NO and CO2
We use insulated stainless steel chambers typically deployed for less than 5 minutes at each measurement location for measuring NO and CO2.
For NO, chamber air is fed to a portable chemiluminesent analyzer (below left) for real time analysis. For CO2, chamber air is fed to a LiCor infra-red analyser (below right).
