Dust and Particles
Particulates/ aerosols are probably the most dangerous components of poor quality air. We now know that the size and composition of these particulates determine their toxicity. Designed by aerosol scientists and engineered by Alphasense, these OPCs have been extensively tested in both clean and high pollution urban environments and are increasingly being used in industrial environments. Tested by research organisations and university laboratories worldwide, all 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.
The OPC-N3 has taken the success of the older OPC-N2 unit and improved it further. Following long term projects in very polluted urban environments, Alphasense has further ruggedised the OPC-N range. With the same dimensions and power/ interface as the N2, the OPC-N3 now measures from 0.35μm to 40 μm, sorting into 24 size bins.
Features include improved aerodynamics with reduction of particle deposition, better small particle detection and extended upper size measurements. The OPC-N3 can measure from clean rooms to pollution levels of 2,000 μg/m3 (PM2.5) with the unique feature of being able to measure pollen.

The OPC-R series gives excellent performance in a small size and at low cost. The OPC-R2 has replaced the OPC-R1 and this provides improved small particle detection, reduced fan noise and better EMC protection than the OPC-R1. Identical power requirements, communication protocols and data format mean that switching from the R1 to the R2 is simple. Using laser scattering technology, the OPC-R series has a clean flow path with 0.3 L/minute flow rate and collimated optics. The removable flow exit adaptor allows easy system integration; the SPI interface and PC analysis software make for simple data collection and analysis. With 16 sized bins, you can record PM1, PM2.5 and PM10 every second, along with size histograms, critical when you need to know more than just the PM.
