Bettair Cities recognized in international air quality sensor testing
Bettair Cities has received 9 awards at the 2025 AIRLAB Solutions Microsensors Challenge, following several months of independent evaluation under a wide range of environmental and air pollution conditions. The results provide detailed insight into the performance of the Bettair Static Node, a multi-pollutant air quality monitoring system designed for outdoor and underground railway station applications.
At a glance
9 AIRLAB awards
Bettair Cities received nine awards following the independent 2025 AIRLAB microsensor evaluation programme.
Best-performing OA-M system
The Bettair Static Node was identified as the best-performing OA-M system overall.
Leading IA-URS performance
The system was also identified as the best-performing system in IA-URS.
Top NO₂ accuracy in France
The Static Node achieved the best accuracy for outdoor NO₂ measurement in France.
Top outdoor O₃ accuracy
It also achieved the best outdoor O₃ accuracy across all outdoor sites evaluated.
International evaluation
Testing took place in France, Ghana, India and an underground railway environment.
Independent evaluation across multiple environments
The fifth edition of the AIRLAB Solutions Microsensors Challenge evaluated 47 microsensor models from Africa, North America, Asia and Europe. Tests were carried out under different environmental and pollution conditions in France, Ghana and India. For the first time, the programme also included an underground railway environment, extending the evaluation to an additional type of demanding air quality monitoring application.
This international approach makes it possible to assess microsensor technologies under different operating conditions rather than relying solely on manufacturer specifications or a single test environment.
Bettair Static Node ranked first in key evaluation categories
According to the AIRLAB assessment, the Bettair Static Node was the best-performing OA-M system overall. It was also identified as the best-performing system in IA-URS. The evaluation highlighted a combination of very good accuracy, environmental performance, excellent utility and usability.
These results form part of the nine awards received by Bettair Cities during the 2025 Challenge and provide independent technical recognition across several evaluation environments.
Best accuracy results for outdoor NO₂ and O₃
The Bettair Static Node achieved the best accuracy for outdoor NO₂ measurement in France. It also obtained the best accuracy for outdoor O₃ across all outdoor sites included in the evaluation.
These results are particularly relevant when assessing microsensor systems for applications where pollutant-specific performance is an important selection criterion.
Multi-pollutant air quality measurement
The Bettair Static Node is a multi-pollutant air quality monitoring system. The AIRLAB evaluation identifies the following measured pollutants:
- Particulate matter: PM1, PM2.5 and PM10
- Nitrogen compounds: NO and NO₂
- Oxidants: O₃
- Carbon compounds: CO and CO₂
This combination enables several air quality parameters to be monitored from the same system, supporting distributed outdoor and underground monitoring applications.
Additional environmental measurements
In addition to pollutant monitoring, the Bettair Static Node includes several additional measurements identified in the AIRLAB assessment:
- Temperature
- Relative humidity
- Atmospheric pressure
- Wind
- Sound intensity
- Geolocation
These complementary parameters can provide useful environmental context alongside pollutant measurements when analysing monitoring data.
Selecting the right microsensor for each application
One of the main conclusions highlighted by AIRLAB is that there is no universal microsensor. Performance depends on the pollutant being measured, the deployment environment and the intended application. Independent evaluations therefore provide useful information for comparing technologies according to specific monitoring requirements.
For Canadian organizations considering distributed air quality monitoring, these results provide additional technical information when assessing Bettair Cities for outdoor or underground monitoring projects.
