Air pollution monitoring using our sulphur dioxide analyser provides long-term assessments of emissions management actions and air pollution control. Hazardous gas monitoring of sulphur dioxide is becoming increasingly important as organisations implement their air quality control actions. For example SO2 monitoring is important in the prevention of acid rain.

Sulphur dioxide analysis involves quantitative determination of the concentrations of sulphate ions chemically adsorbed to the SO2 monitor by Ion Chromatography with reference to a calibration curve. Our air analyses are all conducted by UKAS Accredited Methods, working to ISO 17025.
 
Diffusion tubes are ambient air analysers suitable for carrying out spatial or localized ambient air quality monitoring for sulphur dioxide. SO2 measurement with ambient gas analysers can be an excellent tool for any pollution assessment survey or on-going study. Capable of providing long-term assessments for air quality modelling or determining air management locations. SO2 monitoring is widely used for ambient air sampling of traffic emissions and SO2 emissions from fuel combustion, such as from domestic fires, power stations and oil refineries.
 
The sulphur dioxide air monitor forms part of Gradkos range of ambient air monitoring systems for organic and inorganic pollution. Emissions sampling using diffusion tubes is used in greenhouse gas monitoring programmes, pollution research and air pollution modelling.
