Air Quality Monitoring Solutions for Ultra-Fine Particle Number and Size Distribution Measurements

TSI’s (USA) Environmental Particle Counter (EPC) Model 3783 and Ultra-fine Particle (UFP) Monitor Model 3031 provide unique air quality measurements of ultra-fine particle number (PN) and size distribution. Ultra-fine particles (<100nm) occur in massive numbers in urban air and are not well represented using traditional mass based measurements. Additionally, mounting toxicological evidence appears to indicate that UFP exposure is associated with negative health effects; because of this, instruments like TSI’s EPC Model 3783 and UFP monitor Model 3031 are installed in a variety of air quality monitoring systems across the globe, allowing worldwide UFP concentration comparisons for the first time ever.
