GRIMM Model EDM 180+ Automated PM Measuring System
Brand: DuragThe newest EDM 180+ is a "fit for purpose" state-of-the-art system, capable of making more accurate and higher resolution measurements.
This system offers outstanding features such as simultaneous PM measurements in 31 high resolution particle size channels, 0.1 mg/m³ resolution, an isothermal inlet with an integrated Nafion dryer.
The system runs extremely silent, requires very low maintenance and by using the field test kit together with our System Diagnosis Software, the EDM180+ can also be validated on site.
Features- Approved according to US-EPA
- 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 (can also be used in vehicles)
- 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
- Aerodynamically focused aerosol with no boarder zone error
- 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
