TSI's Laser Aerosol Spectrometer 3340 is an optical spectrometer that measures particle size distributions from 0.09 (90 nm) to 7.5 µm and combines ultra-high sensitivity and superior resolution with ease-of-use. The 100 size channels are configurable and enable users to zero in on a specific size range or match the resolution of another instrument. It is used in many different applications such as determining the efficiency of air cleaners, HEPA/ULPA high efficiency filter testing, indoor/outdoor air quality studies and source apportionment. The model 3340 measures complete size distributions in less than a second by simply powering up and sampling.

 

Product Details

The Laser Aerosol Spectrometer Model 3340 uses patented wide-angle optics and an intracavity laser to measure the size and number concentration of airborne particles. It features a monotonic response with respect to light scattering intensity in the Mie range for precise resolution. While the instrument is calibrated with NIST traceable Polystyrene Latex (PSL) spheres, users can easily perform custom calibrations with other aerosols. This Laser Aerosol Spectrometer is unique in its ability to measure both sub- and supermicron particles over such a wide range, making it a true workhorse in any lab.
