TSI's aerosol particle size analyzer 3340 is a highly sensitive, high-resolution, and versatile aerosol particle size analyzer. This "power on detection" instrument enables users to easily detect particles in the particle size range of 0.09 µ m (90 nm) to 7.5 µ m. With simple startup and sampling, particle size distribution detection can be completed in less than one second.
3340 is a convenient tool that can be used for monitoring filters or operating processes, laboratory measurements, or on-site activity sampling. 3340 is as useful as your primary aerosol tool, but it can also provide valuable supplementary information for aerosol detection based on other particle size detection technologies (such as SMPS, APS, CPC, FMPS, etc.).
