New wide-ranging particulate sensor
Alphasense has launched a new version of its optical particle counter. The new OPC-N3 retains all of the advantages of its predecessor (OPC-N2) with the added benefit of automatic range switching covering PM10, PM2.5 and PM1. With an expanded measuring range (0.38 to 40 µm), the OPC-N3 is able to measure the particulate fractions of most interest; from the finest of particles up to larger particles such as pollen.
