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
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.
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.
AQMesh air quality monitors require very little maintenance and there is a very low ongoing cost. All we recommend is the electrochemical sensors are replaced every two years, and we replace all sensors for free during the first year.
The AQMesh air quality monitoring system has been on the market and in the field since 2012, with some customers still successfully operating the exact same pods they received nine years ago.
