MODEL EDM164

A GENUINE NEAR-REFERENCE METHOD

Small & Compact PM Monitor for Continuous Outdoor Monitoring

The EDM 164, in its compact and mobile weather housing, performs reliable optical detection for counting and classifying dust particles. The EDM 164 is applicable for short and long-term continuous monitoring of dust pollution and enables a real-time data analysis of dust and meteorological measurement data.

This configuration places the EDM 164 in the leading position of the mobile environmental dust monitoring for such applications as dust mass, PM values, total counts and particle size distribution. The EDM 164 is the optimal solution for reliable environmental monitoring, e.g. PM monitoring, source identification, or pollution control at construction and mining sites.

Overview

  • fully automatic monitoring system with remote access
  • extremely energy-efficient, low maintenance
  • no consumables
  • real-time monitoring of PM values (PM10, PM2.5, PM1) and particle number
  • additional information on particle size and mass distribution
  • high precision over 31 size channels
  • versatile data aquisition and communication (data logger with GSM via internet)
  • self-test of all optical and pneumatic components for high quality standards
  • rinsing air for protecting laser and detector in optical cell
  • meteorological sensors
  • 11 size channels < 1 μm for precise submicron detection
  • total inlet flow volume (1.2 L/min) entirely analyzed in optical cell
  • excellent counting statistics and reproducibility at low and high dust concentrations

Applications

  • mobile and simultaneous monitoring of PM10, PM2.5, and PM1
  • hot spot monitoring
  • public site and urban monitoring
  • source identification
  • quantification of diffusive emissions according to VDI 4285 part 3
  • early warning system for forest fires
