Diffusion tubes are low cost ambient air monitoring systems that are widely used in gaseous pollutant monitoring. They are used for passive sampling of air pollution as part of emissions management schemes, dispersion model validation or for air monitoring to review air quality control.

Air quality monitoring using our hydrogen sulphide analyser provides long-term assessments of hazardous gas prevention and air pollution control. Diffusion sampling for ambient air monitoring can be an excellent tool for any pollution assessment survey or on-going study.
 
The hydrogen sulphide air monitor forms part of Gradkos range of air monitors for organic and inorganic pollution. Emissions sampling using diffusion tubes is used in greenhouse gas monitoring programmes, pollution research and air pollution modelling.
