This stand-alone environmental dust monitor detects airborne particles in real time, including semi-volatile compounds thanks to its dual sampling system. It allows simultaneous measurement of the dust mass fractions PM10, PM2.5, PM1 and also the particle size distribution in 31 size channels


Functionality: Light scattering at single particles



  • Unique PM10, PM2.5 and PM1 monitoring, dual sampling system with two sampling lines, isothermal humidity extraction with Nafion and heated SVC evaporator
  • SVC controller for selectable temperatures for the SVC evaporator
  • 31 size channels for particle size distribution
  • Data logger for remote access and real-time data analysis
  • Long term stability and very low zero drift due to purge air for protecting laser and detector
  • Meteorological sensor for wind speed + direction, T, RH, P and precipitation



  • 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
