All comparison trials are from regularly maintained reference stations. Not all are specifically identified due to the administrative overhead of getting permission to name data sources. We do not always use ratified reference data to avoid delays in analysis but re-running the comparison analysis after data ratification often improves correlation.

AQMesh has been independently tested and verified in numerous academic studies and publications
A wide range of private, academic and public organisations across the globe are currently using AQMesh
Development through extensive global co-location comparison trials in all seasons across each continent means AQMesh air quality monitoring systems can operate in the wides possible range of environments and conditions.
The carefully developed data processing algorithms used by AQMesh outdoor air quality monitors are fully traceable and fixed by version number, and, unlike other systems, have been achieved with no use of machine learning or artificial intelligence.
Whilst some manufacturers use a calculation to give an NO2 reading, the AQMesh air quality monitoring system uses a unique O3-filtered NO2 sensor for accurate, direct measurement of NO2.
With AQMesh outdoor air quality monitors, meaningful correction of cross-gas effects and interference from environmental conditions is consistently delivered through proven and traceable processing.
