Short description Perfect research instrument, a real-time sizer, counter, mass monitor and gravimetric validation. Powerful low cost version, a sizer, counter, mass monitor and gravimetric validation. Bio aerosol spectrometer, a sizer and counter with integrated object slide for biological analysis. Portable aerosol spectrometer ranging from 10 nm up to 35 µm to measure in 41 size channels in real-time. Fastest spectrometer even at highest altitudes! Full data sets in 1 sec. on balloon flights, ultra-light airplanes and even jet airplanes. Universal Aerosol Generator 80nm to 5 µm:
• Polystyrene aerosols,
• Salt aerosols,
• DEHS • DOP aerosols
• PAO aerosols
