Low Maintenance Environmental Dust Monitor Edm 665

The EDM 665 Environmental Wide Range Aerosol Spectrometer integrates two technologies for particle counting and classification into a single device: the Scanning Mobility Particle Sizer (SMPS+C) with the butanol condensation particle counter for nanoparticles, and the approved EDM 180 for larger fractions.

Designed and constructed specifically for atmospheric monitoring, the EDM 665 is a state-of-the-art system capable of providing accurate and highly resolved measurements across the entire particle size range from 5 nm to 32 A Aum, offering 31 size channels for EDM 180 and a user-selectable number of channels for SMPS+C (e.g., 64 per decade).
