MODEL EDM365
RUGGED OUTDOOR PM MONITOR
The Stand-Alone Brother of the Approved EDM180
The mobile environmental dust monitor EDM 365 was developed and designed by Grimm for the mobile industrial use. This high-tech stand-alone system EDM 365 satisfies customers world-wide with its high precision and the low maintenance and operating costs. The EDM 365 detects airborne particles in real-time without the loss of the semi-volatile compounds.
Every single aerosol particle is detected in the optical measurement cell. This precise and reliable single particle count allows for a simultaneous measurement of the dust mass fractions PM10, PM2.5, PM1 and also the particle size distribution in 31 size channels.
The outdoor weather protection housing is thermo-isolated with an automatic heating and proportional ventilation.
Overview
- 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 measurement of PM10, PM2.5, PM1, total counts (TC), and particle number distribution
- fully automated monitoring system with remote access
- extremely energy-efficient, low maintenance, no consumables
- no loss of semi-volatile compounds
- no radioactive source, insensitive to vibrations
- versatile data acquisition and communication (GSM data logger)
- self-test of all optical and pneumatic components for high quality standards
- rinsing 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
Applications
- Continuous PM measurements where no container can be placed
- AMS for PM networks
- Industrial surveillance
- epidemiological studies
- monitoring of construction and mining sites
