GRIMM Model EDM 164 Mobile Environmental Dust Monitor
Brand: DuragThe EDM 164 (Enviromental Dust Monitor) combines reliable optical detection for counting and classifying dust particles in a compact and mobile weather housing. The all rounder with no limits for all your applications. The EDM 164 is suitable for short or long term continous monitoring of dust pollution and enables real time data analysis for dust and meterological measurement data.
Features- Fully automatic monitoring system with remote access
- Extremely energy-efficient, low maintenance, no consumables
- Real-time monitoring of PM values (PM₁₀, PM₂.₅ and PM₁) and particle number
- Additional information for particle size and mass distribution
- High precision over 31 size channels with great reproducibility
- Versatile data acquisition and communication (data logger with GSM via Internet)
- Self-test for all optical and pneumatic components ensures high quality standards
- Internal rinsing air protects the laser and detector in the optical cell
- Meteorological sensors for wind speed and direction, precipitation, T and RH
- 11 size channels < 1 mm for precise submicron detection (forest fire monitoring)
- Total inlet volume flow (1.2 liter/min) is entirely analyzed in the optical cell
- Excellent counting statistics and reproducibility at low and high dust concentrations
