Laser Aerosol Spectrometer

TSI’s Laser Aerosol Spectrometer Model 3340 is a general purpose aerosol particle sizer which combines ultra-high sensitivity and superior resolution with ease-of-use. This high performance workhorse measures complete size distributions in a tenth of a second over a size range of 0.09 (90 nm) to 7.5 μm easily and accurately. Configurable size channels enable users to zero in on a specific size range or match the resolution of another instrument.
