High-precision instruments for air quality monitoring, particle measurement, and environmental analysis – built for reliability, accuracy, and compliance.
The DURAG GRIMM EDM 280 is a premier, stationary aerosol spectrometer designed for the continuous, real-time monitoring of airborne particulate matter (PM). Utilizing advanced optical light-scattering technology, this system delivers unmatched precision in detecting particle mass concentrations and size distributions. Fully QAL1 certified (TÜV/MCERTS), the EDM 280 meets the most stringent European regulatory requirements for air quality monitoring (EN 16450).
Engineered for environmental agencies, industrial plant operators, and EHS managers, the EDM 280 provides high-fidelity data essential for legal compliance and source apportionment. By reporting multiple PM fractions and the complete particle size distribution simultaneously, it represents the gold standard in modern immission monitoring technology.
Metrological Precision: Features aerodynamic focusing (ISO 21501-1) to ensure every particle is counted individually, eliminating edge-zone errors and coincidence losses.
Regulatory Compliance: Fully certified according to EN 16450, EN 15267, and VDI 4202-3. It is approved for use in official governmental monitoring networks.
High Temporal Resolution: Delivers validated PM10 and PM2.5 values with a time resolution starting at 1 minute—critical for identifying transient emission spikes and pollution sources.
Low Operational Costs: Extremely low power consumption (approx. 25W during standard operation) and a low-maintenance design featuring an internal rinse air system to protect the optics.
Seamless Integration: A compact 19-inch rack-mount design ensures easy installation into existing monitoring stations or mobile laboratory containers.
The EDM 280 stands out by employing a monochromatic laser diode that remains unaffected by variations in particle composition or color. While conventional sensors often struggle in extreme climates, the EDM 280 maintains stability across a wide temperature range (-40 °C to +60 °C) thanks to its sophisticated all-weather sampling system with integrated Nafion drying technology.
The system offers 72 size channels, providing detailed insight into particle distribution from 0.178 µm to 29.4 µm. This transforms the instrument from a simple mass monitor into a powerful diagnostic tool for scientific research and advanced industrial process analysis.
National Air Quality Networks: Official monitoring of PM10 and PM2.5 in urban, industrial, and background locations.
Industrial Perimeter Monitoring: Tracking dust dispersion at factory boundaries, ports, mining sites, or large-scale construction projects.
Source Apportionment: High-resolution data analysis to determine the origin and nature of local air pollutants.
Mobile Air Quality Studies: Vibration-resistant construction makes it ideal for installation in mobile monitoring vans or temporary containers.
Aerosol Research: Studying atmospheric aerosol behavior and the impact of traffic or industrial emissions on public health.
Unlike many optical dust monitors that offer only indicative data, the EDM 280 has been rigorously validated against the official gravimetric reference method. You are guaranteed data that holds up under technical and legal scrutiny. With a laser service life exceeding 10 years and the ability to perform on-site calibrations without returning the unit to the factory, the EDM 280 significantly reduces the total cost of ownership (TCO) for long-term monitoring projects.
