AQMesh is the proven small sensor air quality monitoring system for pollutants including NO2 and PM2.5

AQMesh has been independently tested and readings compared to reference by leading air quality professionals

AQMesh provides the key measurements needed to understand local air quality - all from a single, easily-mounted unit

AQMesh is an air quality monitor manufactured in the UK and supported worldwide through a global network of distributors. It has been designed to offer a robust and easy-to-use air quality monitoring system that can deliver localised real-time readings, improving the scope and accuracy of gathering air quality data in order to support initiatives to reduce air pollution and its risk to human health.

Latest AQMesh co-location studies show capability of small sensor systems

5th November 2018

Recent co-location comparison trials against certified reference equipment continue to prove AQMesh performance and reliability for localised air quality monitoring. Trials in the USA, UK and Western Europe this year have delivered high correlation coefficients (R2 values) for key pollutants such as nitrogen dioxide (NO2), ozone (O3) and fine particulate matter (PM2.5). An R2 value of 0.92 against…

Urban Observatory monitors Newcastle with new generation of environmental sensors

20th September 2018

The UK’s first Urban Observatory, led by Newcastle University, has been designed to provide a digital view of how cities work. AQMesh air quality monitoring equipment is being deployed across Newcastle and Gateshead in conjunction with other instruments for monitoring parameters such as air and water quality, noise, weather, energy use, traffic and even tweets. Forming part of a network of…

AQMesh shows high accuracy local ozone readings across global locations

16th August 2018

AQMesh has been measuring ozone (O3) using small sensors since 2011 and the readings from the latest generation electrochemical sensor, using AQMesh v4.2.3 processing, as compared to co-located certified reference readings, consistently show an R2 of over 0.9 with an accuracy ±10ppb (20µg/m3). AQMesh pods have been measuring ozone levels around the world and co-location comparison studies show…

AQMesh to be used in new ‘hyperlocal’ air quality network for London

28th June 2018

London Mayor Sadiq Khan has launched a new, street-by-street monitoring system that will help to improve that capital’s air quality. From July 2018, and operating for a year, London will benefit from what is being described as the world’s most sophisticated air quality monitoring system. A consortium involving academia, an environmental charity, and commercial partners will install a network of…

Co-location comparison trials

AQMesh performance has developed through a series of co-location comparison trials in which AQMesh pods are installed next to an air quality monitoring reference station, with the comparative data then analysed to produce an R2 value showing the close relationship between the instruments.
