Mobile PM & SVC monitor AirQualifier EDM 264-SVC

AirQualifier EDM 264-SVC
Mobile PM & SVC monitor

This mobile aerosol spectrometer determines dust mass fractions and particle number size distribution without semi-volatile compounds. 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

  • Sampling probe (SVC) with switchable catalytic stripper for SVC elimination
  • 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 grade data logger; WLAN, LTE, 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 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
  • Mobile PM monitoring
  • Aerosol science
  • Source apportionment
  • Secondary PM formation by gaseous precursors 
  • VOC and SVOC contribution in dust mass fractions 
  • Technical data
