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.

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.

Robust hardware, wireless communications and the secure AQMeshData server mean AQMesh air quality monitors can easily reconnect themselves and continue to capture data if power is ever interrupted.

Encrypted disks, complex authentication, audit logs and proactive systems for continuous detection of vulnerabilities and intrusions are routinely examined, making the AQMeshData server – and users’ data – as secure as possible.

With measurements processed and stored on the secure AQMeshData server there is no need for site visits to retrieve data and should anything untoward happen to the outdoor air quality monitor, data is still perfectly safe and accessible.
