MODEL EDM180
THE FIRST EQUIVALENT METHOD EVER
ENVIRONMENTAL DUST MONITOR FOR APPROVED PM MEASUREMENTS
The GRIMM EDM 180 is the leading Automated Measuring System (AMS) for measuring particulate matter concentration (PM10, PM2.5) in ambient air. This proven system offers for over a decade outstanding features such as simultaneous PM measurements in 31 particle size channels, 0.1 μg/m3 resolution, and an isothermal inlet with an integrated Nafion dryer.
The EDM 180 runs silent, requires low maintenance and can be validated on site using the field test kit together with our system diagnosis software. The EDM 180 is the optimal solution for reliable environmental monitoring, e. g. automated PM measurements in environmental networks, epidemiological studies, urban and rural PM monitoring.
The EDM 180 is in service of governmental networks and institutes in over 30 countries.
Overview
- certificates and approvals: US-EPA, UK-MCERTS, CN-CMA; demonstration of equivalence in over 20 countries
- 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 (applicable also in vehicles)
- 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
- AMS for PM networks
- PM monitoring
- epidemiological studies
- monitoring of construction and mining sites
