Taking the guesswork out of particle counting


Trust Alphasense Optical Particle Counters to deliver accurate results every time


Unlike most low-cost particle sensors which measure particle count in a single size category and use that estimate the volumes of others, Alphasense OPCs measure the full range from PM1 to PM10, giving end users reliable and repeatable data, not simply extrapolated values.


Alphasense’s range of OPCs was developed hand-in-hand with aerosol scientists and engineered to deliver the accuracy you expect from reference grade equipment in more workable size formats and at a fraction of the price.


Both the wide ranging OPC-N3 and the smaller footprint OPC-R2 provide digital outputs of PM1, PM2.5 and PM10 (and optionally PM4.25) along with a histogram of particle count for each of up to 24 user-configured size categories. Alphasense’s proprietary flow correction technology ensures stable readings even in high-dust environments and is a key factor in a number of Universities and Research Organisations independently verifying Alphasense OPCs as providing best in class performance.
