Gas Monitoring

Continuous real-time measurement of gaseous compounds in ambient air is of paramount importance in the field of air quality monitoring.

Specialist advanced technology is required to identify and quantify concentrations of air pollution often in the parts per billion (ppb) range.

Enviro Technology supplies ambient air quality monitoring analysers for many gases including:

Oxides of Nitrogen (NOx), Nitrogen dioxide (NO2), Sulphur dioxide (SO2), Ozone (O3), Carbon monoxide (CO), Ammonia (NH3) and Volatile Organic Compounds (VOC’s) including specific hydrocarbons for instance Benzene, Toluene and Xylene.

Real-time analysers are also available for other less common pollutants such as Formaldehyde, Phenol, Styrene, 1-3 butadiene, Hydrogen fluoride (HF) and Mercury vapour (Hg).

Applications include:

• Air quality monitoring: kerbside, roadside, urban and rural.
• Fenceline and fugitive emissions.
• Dispersion model validation.
• Environmental impact assessments (EIA’s).

Over almost 30 years, ET has become a world-class specialist in air quality monitoring technology and has a wide range of products and technologies for almost every conceivable application.

As well as traditional “point-measuring” technologies (pneumatic sampling lines) ET is almost unique in being to offer open-path and remote-sensing technologies for fenceline, fugitive emissions and vehicle emissions monitoring applications.
