Particulates & aerosols are most dangerous components of poor quality air and we know that the size and composition of these particulates determines their toxicity. At Alphasense, we pioneered a range of Optical Particle Counters (OPCs) designed by aerosol scientists and engineered by Alphasense, delivering high-quality particle counts and sizing at affordable prices. The range has continuously evolved since to offer the best quality, low cost devices on the market.

Tested by research organisations and university laboratories worldwide, Alphasense OPCs provide digital outputs of PM1, PM2.5 and PM10 (and optionally PM4.25) along with histograms of the particle count for each size. Our (patent pending) flow correction ensures stable readings, even in high dust environments.

Alphasense OPCs are being using commercially in a broad range of both clean and highly polluted urban environments and are increasingly being used in industrial applications.

In response to long-term projects in highly polluted urban environments, Alphasense has further ruggedized the OPC-N range and improved functionality in line with the demands of commercial applications. The latest OPC-N3 has the same dimensions and power/interface as the older OPC-N2, however it now measures from 0.35μm to 40 μm and sorts into 24 size bins.
