TSI 3302A Aerosol Diluter

TSI 3302A Aerosol Diluter

The TSI 3302A Aerosol Diluter reduces particle concentrations of high-concentration aerosols, providing a representative sample that meets the input requirements of the TSI 3321 Aerodynamic Particle Sizer (APS) Spectrometer. This APS accessory achieves dilution ratios of 100 to 1 and 20 to 1 using easy-to-change capillary tubes. Two diluters in a tandem configuration provide dilution ratios as high as 10,000 to 1.

Engineered to provide very low particle loss in the 0.5- to 10-µm size range, the 3302A is totally self-contained and requires no outside power or compressed gas. Durable construction and simple maintenance procedures translate into years of trouble-free operation. It works with both old and new APS spectrometers.
