Product Description：

PM2.5 which can go directly to the lungs contains more toxic heavy metals and the hazardous organic pollutants, what’s more, it is more easily attached to bacteria and viruses in the environment, so the particles are greater impacted on the ecological environment and human health. After OPC-N2, Alphasense has launched a particle counter OPC-R1 with a very small size, which able to measure PM1, PM2.5 and PM10. It has a faster flow rate than that of OPC-N2 and OPC-N3, but with much lower power consumption.

Main spec of OPC-R1:
