OPC‑N3 Particle Monitor

Optical Particle Counter, Particulate Matter (PM) mass and 24-bin particle size analysis, PM1, PM2.5, PM10 and particle size distribution monitoring

High PM mass, High‑Resolution, Environmental Particulate Sensor

The Alphasense OPC‑N3 is an optical particle counter engineered for high‑pollution urban monitoring, offering detection from 0.35–40 μm with high resolution 24‑bin size categorization. Its ability to detect PM1, PM2.5, PM10, and pollen‑sized particles makes it ideal for environmental and regulatory monitoring systems. Its strong correlation with laboratory-grade OPCs, make it an affordable R&D tool.
