Air Pollution Monitoring Products
Our gas monitors allow easy recording and reporting of multiple gas species, viewed remotely through AirQWeb.
Like particulates, pollutant gases significantly affect the quality of air we breathe, and are often present in the same environments and generated by the same sources, such as industry and road traffic.
We have recently developed gas monitoring instruments to complement our range of dust monitors. The iGAS can measure up to eight different pollutant species simultaneously, with all data stored and displayed on AirQWeb, alongside data for any dust or noise & vibration instruments.
The monitors use a variety of methods, such as electrochemical cells, nondispersive infrared sensors, and photoionization detectors to measure different gas species, including:
- Oxides of nitrogen (NOx)
- Ozone (O3)
- Sulphur dioxide (SO2)
- Carbon dioxide (CO2)
- Volatile organic compounds (VOCs)
- …and more
The measured gases can be configured for different instruments. Software algorithms correct cross-interference between species, and a zero-gas generator eliminates drift in the cells.
