This mobile aerosol spectrometer determines dust mass fractions and particle number size distribution. It is designed for both short and long-term continuous monitoring of dust pollution and enables real-time data analysis of particle number, dust mass and meteorological data.


Functionality: Light scattering at single particles



  • Unique measurement range in one device: TSP, PM10, PM4, PM2.5, PM1, PMcoarse and total counts, inhalable, thoracic, respirable, pm10, pm2.5 and pm1
  • 31 equidistant size channels; PSL traceable particle size distribution
  • High-class data logger; data transmission, remote access and real-time data analysis via mobile radio (LTE)
  • Long term stability and very low zero drift due to purge air for protecting laser and detector
  • Meteorological sensor for P, T, RH, wind speed & direction and precipitation
  • GPS position



  • Suitable for versatile applications
  • All in one solution, ready to use, rugged design
  • Aerodynamic aerosol focusing, total inlet flow (1.2 l/min) analyzed in the optical cell, no border zone error
  • Cost saving, low maintenance
  • Optional accessory: Interchangeable sampling probe (SVC) with switchable catalytic stripper for SVC elimination



  • Mobile PM monitoring
  • Construction site monitoring
  • Fugitive emissions
  • Fence-line monitoring
