The New Portable Environmental Dust Monitor 11-E
Mini Laser Aerosol Spectrometer (Mini-LAS)

The Mini Laser Aerosol Spectrometer (Mini-LAS) 11-E is the result of continuous development of
GRIMM’s world-wide known and appreciated spectrometer. The combination of advanced data
communication, innovative design and reliable optical measurement technique makes the 11-E the
world champion of all portable fine dust measuring devices.
With our proven measurement cell, based on the laser scattering light method, we reliably count
every single particle in a wide size range from 0.25 to 35 µm and classify them into 31 separate size
channels. This patented method guarantees a precise assignment of particles according to their size,
and thus the single PM mass fractions can be accurately calculated. Data storage and retrieving of
the mass specific PM10, PM2.5 and PM1 values and (optionally) the particle size distribution in 31
size channels is done in real-time advanced data communication interfaces.

Customer’s benefits

The efficiency of the device meets the standards PM10 (EN12341) and PM2.5
(EN14907), the US EPA, the Russian GOST and the Chinese requirements.
Simultaneous display and output of measurement data of all PM dust mass fractions
every minute
Particle size distribution in 31 size channels (optional)
Advanced data communication interfaces (SD-card, USB, Bluetooth and Ethernet)
Small, portable, tough, battery powered and remote controllable via Bluetooth
Integrated, removable 47 mm PTFE-filter for subsequent gravimetrical and chemical
analysis (dual technology)
Self-test at each start-up
Permanent rinsing air for keeping the optical measurement cell clean

The 11-E offers the user all possibilities when saving or retrieving the measurement data. The
measurement data can be conveniently accessed and shown online via Bluetooth or Ethernet at
the workplace via laptop or tablet. Even accessing the data in real-time per App (Android) is
possible. Additionally, the measurement data can be stored on SD-card and/or on USB flash
drive.
