Alphasense OPC-N2

The Alphasense OPC-N2 is an optical particle counter. According to the manufacturer, the flow correction of this sensor ensures stable readings, even in high dust environments.
The OPC-N2 measures particles from 0.38 micron to 17 micron diameter at a 1 second interval.  The OPC-N2 provides both PM readings and real time particle size histograms.
