AQMesh pods can measure just one gas or up to six gases, particles, noise and wind speed & direction. Humidity, pressure and pod temperature are always measured
Accurately measure the target pollutant
Meaningful correction of cross-gas effects and interference from environmental conditions is
consistently delivered through proven and traceable processing.
Processing of sensor output can vary from none at all to the latest AI approaches. Very few air quality experts would challenge the need to apply some form of correction to raw sensor output: it is well known that all small sensors are affected by environmental conditions of one sort or another. Corrections can be applied at various stages. AQMesh was the first manufacturer to test individual sensors in ambient air and quantify sensitivity – rejecting any sensors that do not meet criteria – before installing sensors in equipment.
The sensor characteristics captured at this initial stage can be used during the repeatable, traceable processing that is applied to sensor output from the working system. Years of work and hundreds of co-location datasets are behind the latest algorithms, which are always given a version number and which are available as a free upgrade to all equipment users as soon as they are released.
Some systems claim to offer accuracy through laboratory calibration, and they may well deliver accuracy in the laboratory, but applications are in the field and the perfect relationships achieved with single, dry gases in the lab do not necessarily mean anything in an outdoor environment of mixed pollutants and rapidly changing environmental conditions. If you just need a rubber stamp to show a process has been carried out that’s fine, but do not expect lab calibration to be a guarantee of accuracy in the field.
More AQMesh benefits
With wireless communications using the global mobile network and a choice of power options, including batteries, mains supply or a bespoke solar pack, AQMesh can be installed in almost any location
Whilst some manufacturers use a calculation to give an NO2 reading, AQMesh uses a unique O3-filtered NO2 sensor for accurate, direct measurement of NO2
AQMesh 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
AQMesh pods 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
AQMesh 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
