Aerocet 531S Mass Particle Counter

Aerocet 531S

The AEROCET 531S is a full–featured, battery operated, handheld mass monitor or particle counter. This amazing unit simultaneously measures 6 mass concentration ranges (PM1, PM2.5, PM4, PM7, PM10 and TSP) or five particle count sizes (0.3µm, 0.5µm, 1.0µm, 5.0µm and 10µm). View sample history data in either mode.



    Operation Principal : Counts individual particles using scattered laser light and calculates the equivalent mass concentration using a proprietary algorithm
