EDM 180+
Approved next generation PM monitor
Provides all features of the EDM 180 plus additional USB and Ethernet interfaces. This approved environmental dust monitor is the leading product for measuring particulate matter concentration (PM10, PM2.5) in ambient air. It is in service in government networks and institutions in over 30 countries.
Functionality: Light scattering at single particles
Features
- 19-inch measuring device with 19-inch attachment, sampling probe, meteorological sensor, and accessories; configurable by the customer (firmware, meteorological sensor, etc.)
- Approvals: PM10 (MCERTS, ...), PM2.5 (US-EPA, MCERTS, ...)
- Real-time monitoring of PM values (PM10, PM2.5, PM1), total counts (TC), and particle number distribution
- ʺFull flow analysisʺ of the entire sample volume
- USB and Ethernet
- Fully automatic monitoring system with remote access
- Purge-air circuit to protect optical components
- Self-test of all optical and pneumatic components for high quality standards
- Total inlet flow analyzed in optical cell
- Versatile data acquisition and communication (GSM data logger)
Benefits
- Suitable for many applications
- Extremely energy-efficient, low maintenance, no consumables
- No loss of semi-volatile compounds, no radioactive source, insensitive to vibrations (applicable also in vehicles)
- Excellent counting statistics and reproducibility at low and high dust concentrations
Applications
- AMS for PM networks
- PM monitoring
- Epidemiological studies
- Monitoring of construction and mining sites
