PM monitoring station EDM 365

EDM 365
PM monitoring station

This stand-alone environmental dust monitor detects airborne particles in real time without the loss of the semi-volatile compounds. It is designed for mobile industrial use and 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

  • Equivalent to norms US-EPA, UK-MCERTS, CN-CMA
  • Weather-protected system in powder-coated stainless steel housing
  • Continuous use in harshest environments
  • Real-time monitoring of PM values (PM10, PM2.5, PM1) and particle number in 31 size channels
  • Fully automatic monitoring system with remote access
  • Extremely energy-efficient, low maintenance, no consumables
  • No loss of semi-volatile compounds
  • No radioactive source, insensitive to vibrations
