GRIMM Model EDM 665 Wide Range Aerosol Spectrometer
Brand: DuragThe EDM 665 Wide Range Aerosol Spectrometer combines two technologies for particle counting and classifying in one device.
A Scanning Mobility Particle Sizer (SMPS+C) with a butanol condensation particle counter for nanoparticles and an approved optical Aerosol Spectrometer (EDM 180) for dust particles.
Designed and specifically built for atmospheric monitoring, the EDM 665 is a "fit for purpose" state-of-the-art system capable of making more accurate and higher resolution measurements than any other monitoring device on the market.
Features- Real-time monitoring of the entire particle size range, fully automatic 24/7 monitoring-system
- Low maintenance, 30 days unattended operation, remote access
- Energy-efficient, sampling with isothermal drying system
- High precision with CPC and OPC at low and high concentrations
- Excellent counting statistics and reproducibility
- Low diffusion loss
- Versatile data acquisition and communication (data logger with GSM via Internet)
- Self-test for all optical and pneumatic components ensures high quality standards
- Meteorological sensors for wind speed and direction, precipitation, T and RH
- Instrument parameters secured against data loss. On return of mains voltage the instrument automatically continues with measurement
