Ambient Air Quality Monitoring Stations
Fixed multi-pollutant ambient monitoring stations measuring PM2.5, PM10, NO2, SO2, O3 and CO to WHO Air Quality Guideline standards.
Most African cities operate without a single regulatory-grade air quality monitoring station.
Across sub-Saharan Africa, the majority of cities operate without a single regulatory-grade air quality monitoring station, making evidence-based pollution management and enforcement impossible. The WHO estimates outdoor air pollution causes 600,000 premature deaths across Africa every year, driven by vehicle emissions, industrial activity, biomass burning and dust. Jos•Hansen supplies Thermo Fisher and Environnement SA ambient monitoring stations measuring all six WHO criteria pollutants continuously, providing the data infrastructure governments, municipalities and industry need.
6 criteria pollutants
Every Jos•Hansen ambient station measures PM2.5, PM10, nitrogen dioxide, sulphur dioxide, ozone and carbon monoxide continuously, providing the complete criteria pollutant dataset required for WHO Air Quality Guideline compliance assessment.
Reference method certified
All Thermo Fisher and Environnement SA analysers carry European or US EPA equivalent reference method certification, producing legally defensible data accepted by national environment agencies for compliance and enforcement.
Automated reporting
Cloud SCADA platforms generate real-time air quality index displays, automated regulatory submission reports and threshold exceedance alerts without manual data compilation.
Reference method analysers produce legally defensible compliance data.
All monitoring stations transmit 1-hour and 24-hour mean values via 4G cellular to national air quality data repositories in the format specified by the national environment agency. Real-time air quality index displays can be fed directly from station data to government websites and public information boards. Jos•Hansen provides integration with existing national monitoring networks, including protocol conversion for legacy data management systems.
Containerised stations deploy rapidly in any urban or industrial setting.
Jos•Hansen ambient monitoring stations are configured in weatherproof equipment cabinets or temperature-controlled containers pre-wired with all analysers, data acquisition systems, power conditioning and communications equipment. Factory pre-assembly reduces site installation to 1-2 days, minimising disruption and avoiding quality risks of field-assembled installations. Configurations include roadside kiosk stations for traffic corridor monitoring, industrial fence-line configurations for perimeter monitoring and rooftop installations for urban background monitoring.
SCADA integration delivers real-time data to national monitoring networks.
All monitoring stations are configured with data acquisition computers running AirVision or equivalent SCADA software, transmitting 1-hour and 24-hour mean values via 4G cellular to national air quality data repositories in the format specified by the national environment agency. Real-time public air quality index displays can be fed directly from station data to government websites and public information boards. Jos•Hansen provides system integration with existing national monitoring networks, including protocol conversion for legacy data management systems.

Why Ambient.
Legally defensible data
Reference method certification ensures data is accepted by national environment agencies and international bodies for compliance and enforcement.
Rapid deployment
Factory pre-assembled containerised stations reduce site installation to 1-2 days, minimising disruption compared to field-assembled configurations.
National network integration
SCADA systems transmit data directly to national air quality data repositories in the format required by the national environment agency.
Public health evidence base
Real-time AQI data enables government communication of air quality status and public health advisories during pollution episodes.
