Grimm 11-D Portable Aerosol Spectrometer Dust Decoder

Grimm 11-D Portable Aerosol Spectrometer Dust Decoder

The model 11-D, in its compact and rugged design, combines all advantages of the previous portable GRIMM aerosol spectrometers with the improved optical detection, long-term battery operation, and facilitated handling.

This configuration places the 11-D in the leading position of the portable aerosol spectrometers for monitoring inhalable, thoracic and respirable dust, PM values, and particle number concentration.

The 11-D is the optimal solution for reliable, flexible and real-time measurements for aerosol research and indoor air quality, e. g. at workplaces, interior of vehicles, or for process analysis.
