TSI 3340 Laser Aerosol Spectrometer

TSI 3340 Laser Aerosol Spectrometer

The TSI 3340 Laser Aerosol Spectrometer is a high sensitivity, high resolution general purpose aerosol particle sizer. This ‘turn on and measure’ instrument allows users to easily measure a size range of 0.09 (90 nm) to 7.5 µm. Complete size distributions are measured in less than a second by simply powering up and sampling.

The 3340 is a handy tool to have for monitoring your filters or your processes; measuring in a lab; or sampling on field campaigns. It’s as useful as your primary aerosol tool, but the 3340 can also provide valuable supplemental information to aerosol measurements based on other sizing techniques (i.e. SMPS, APS, CPC, FMPS, etc.).
