How it works

The GRIMM Aerosol Technik The AirQualifier (Model EDM 264) is a mobile aerosol spectrometer for both short and long-term continuous monitoring of dust pollution. 

The model EDM264 features a powerful and robust measuring cell based on optical particle counting (OPC) technology with all the advantages that users of our portable aerosol spectrometers are accustomed to.

The system is embedded in a compact, weatherproof housing equipped with a heated sampling inlet, sigma 2-head, a data logger and meteorological sensor.

The EDM264 provides all fine dust fractions for ambient air measurements: TSP, PM₁₀, PM₄, PM₂.₅, PM₁, PMcoarse , calculated with the proven GRIMM enviro-algorithm, as well as six additional dust mass fractions: pm10, pm2.5, pm1, inhalable, thoracic and respirable for IAQ and workplace measurements.
