portable Aerosol spectrometer model 11-A detects in real time airborne aerosol.particles in the size range 0.25 μm to 32 μm in 31 size channels and represents theresults in particle concentration or particle mass.In addition all particles were collected after optical detection on an integrated 47mm.PTFE-filter inside of the spectrometer (Dual-Technology) for further investigation e.g.chemically, microscopically or gravimetrically.Other Grimm Aerosol spectrometer the model 11-A can be operated with battery.or power supply. The data are shown on a display and are stored on a data storage.card in the spectrometer. Due to the extensive accessories various applications can.be handled like e.g. isokinetic sampling in stacks, at high wind speeds or in pressure.air, simultaneous measurement of temperature, relative humidity and wind speed,long term measurements with a outdoor housing or the use of other additional.sensors e.g. for PAH or surface area of nano.
