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
