Measuring particulate matter (PM) accurately comes with a number of challenges, including effects from humidity and differing particle sizes. Technological considerations are also a factor, such as variable sample flow rates and the physical size and diameter of the sample path, which could affect the number of particles able to be measured.
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.
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.
