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

- Real-time monitoring of PM values (PM10, PM2.5, PM1), total counts (TC), and particle number distribution
- USB and Ethernet
- 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 (applicable also in vehicles)
- Versatile data acquisition and communication (GSM data logger)
- Self-test of all optical and pneumatic components for high quality standards
- Purge air for protecting laser and detector in optical cell
- Temperature and relative humidity sensors
- Total inlet flow analyzed in optical cell
- Excellent counting statistics and reproducibility at low and high dust concentrations
