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.

AQMesh measures influence of cruise ship emissions on local air quality

22nd November 2018

AQMesh has been used in a project at the Port of Kiel, Germany, to measure emissions of nitrous oxides (NOx) and fine particulate matter (PM) around its cruise ship terminal. This year the port attracted 166 visits by 33 different cruise ships, bringing a record breaking 600,000 visitors into the city. Emissions from the cruise ship terminal and its impact on the local air quality has been in discussion…

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…

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…

Proven results

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.

Results from a 2017 co-location trial in Benelux showing the outstanding correlation of AQMesh against reference equipment when measuring NO2, giving an R2 value of 0.9

A co-location comparison trial in 2017 for NO in Slovakia proves AQMesh performance against reference, delivering R2 value of 0.93.
