PORTABLE AEROSOL SPECTROMETER
DUST DECODER 11-D
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.
FEATURES
• real-time monitoring of particle number, occupational
dust mass fractions, and PM values
• additional information on particle number, particle
surface, and dust mass distribution
• 31 equidistant size channels, PSL traceable
• integrated 47 mm PTFE filter (GRIMM dual
technology)
• versatile data aquisition and communication
interfaces (Bluetooth, USB, Ethernet, RS-232)
• rinsing air for protecting laser and detector in
optical cell
• internal sensor for temperature (T) and relative
humidity (RH) in optical cell
• total inlet flow (1.2 L/min) analyzed in optical cell
• self-test of all optical and pneumatic components
for high quality standards
APPLICATIONS
• aerosol science
• PM2.5 in indoor environments according to VDI
4300, part 11
• Indoor Air Quality (IAQ) in buildings and vehicles
• process control in industry
• workplace monitoring (inhalable, thoracic,
respirable) according to EN 481
• monitoring of Permissible Exposure Limit (PEL)
with high time resolution
• dust pollution measurements
