We are often asked by customers whether AQMesh can operate in cold conditions. Long-term use at temperatures well below freezing, with ice and snowfall, is indeed challenging.
A UK local authority installed nine AQMesh systems at different points across a busy town, measuring nitrogen dioxide (NO2) at 15 minute intervals, monitoring 24/7. These locations were established monitoring points, where measurements had been taken previously using diffusion tubes, limited to one average reading every few weeks.
2023 is set to be a big year for AQMesh’s monitoring of particulate matter, with developments in both hardware and data processing offering improved accuracy across key PM fractions.
2022 marked 10 years of innovation and leadership from AQMesh. To highlight the team’s experience, ongoing forward-thinking and its commitment to pushing the capabilities of small sensor systems, here are the top 10 things AQMesh developed first and refined since it commercially launched in 2012.
Many small sensor air quality monitoring systems cannot reliably measure coarse particulate matter, or PM10, because of the technology they use. AQMesh’s proprietary optical particle counter (OPC) delivers high out-of-the-box accuracy across all key particle matter (PM) fractions thanks to its bespoke, in-house design.
Data collected as part of the UKRI SPF Clean Air Program has proven that AQMesh out-of-the-box performance for PM2.5 exceeds new US EPA targets*, with excellent results for PM1 and PM10 as well.
Refinement and development of the AQMesh small sensor air quality monitoring system over many years, and through numerous global co-location comparisons, brings a wealth of unique benefits.
