The Ultimate New Portable Model 11-R
Mini Laser Aerosol Spectrometer (Mini-LAS)
The Mini Laser Aerosol Spectrometer (Mini-LAS) 11-R 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-R the
world champion of all portable fine dust measuring devices.
Because of the high-tech laser optics and the construction of the spectrometer, the 11-R captures
every single particle ranging from 0.25 to 32 µm and classifies it into 31 size channels.
