OPC-N2 Particle Monitor measures PM1, PM2.5 and PM10, augmenting our range of gas and VOC sensors for indoor and urban air quality monitoring.

OPC-N2 Alphasense PM2.5 Particle Sensor Description

Alphasense is dedicated to supplying sensors for air quality networks. Increased awareness of the health danger from particulates has raised significantly the importance of monitoring PM. Our Optical Particle Monitor OPC-N2 measures PM1, PM2.5 and PM10, augmenting our range of gas and VOC sensors for indoor and urban air quality monitoring.

The OPC-N2 originated from research at the Centre for Atmospheric and Instrumentation Research, University of Hertfordshire and has subsequently been developed and refined with five years of Alphasense and UoH collaboration, including the capture of more than 150 million readings at Heathrow airport.

The OPC-N2 measures particles from 0.38 micron to 17 micron diameter accurately, repeatedly, and with minimal maintenance using the patented 'pump-less' design. A proven technology, the OPC-N2 provides both PM readings and real time particle size histograms, competing in performance with existing analytical units but at a fraction of the cost.

* Micro USB socket allows on-site firmware updates
* Onboard data logging using optional 16GB SD card: 12 months' capture
* SPI control of fan and laser for lowest power
* Factory set:
