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
Features
- 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-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
Benefits
- 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
Applications
- Mobile PM monitoring
- Aerosol science
- Source apportionment
- Secondary PM formation by gaseous precursors
- VOC and SVOC contribution in dust mass fractions
