Ambient Stations


Ambient air monitoring involves the measurement of "representative" air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.

The OPSIS System measures multiple gases over an open path, using the DOAS (Differential Optical Absorption Spectrosocopy) technique. It can be configured to measure multiple gases in one system including NO, NO2, SO2, O3, Benzene, Toluene, Xylene, Formaldehyde, NH3 etc.
