SMPS 3938W50-CEN10 Wide-Range Ambient Particle Sizer
The TSI SMPS™ 3938W50-CEN10 is a wide-range Scanning Mobility Particle Sizer designed for continuous ultrafine particle monitoring in ambient air. Fully compliant with CEN/TS 17434:2020, this high-precision instrument meets European standards for atmospheric nanoparticle sizing. With a particle size range from 10 nm to 800 nm, advanced data logging capabilities, and integration with monitoring networks, it is the ideal solution for urban air quality stations, environmental research, and regulatory compliance. Equipped with the advanced DMA 3083 (based on the TROPOS Vienna-type DMA) and ECAC-accredited calibration, the 3938W50-CEN10 delivers standardized, traceable nanoparticle measurements with minimal downtime. Its robust design allows 24/7/365 operation—providing accurate, harmonized data for agencies, scientists, and environmental professionals monitoring particle pollution.
