AQMesh co-location comparison trial results for NO2 in California, USA (V5.0)
|Correlation co-efficient (R2)||0.90|
|Date||March 2017 - April 2017|
|AQMesh processing algorithm||V4.2.3|
|Averaged sample interval||30 minutes|
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.

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.
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.
The AQMesh air quality monitoring system processes and stores all readings on its bespoke secure server which can be accessed by a website login or API to integrate with other systems, or it can be simple emailed to you at your preferred schedule.
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.
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.
AQMesh air quality monitoring system performance and long-term baseline stability has been proven over many years of independent global co-location trials against certified reference equipment.
