Particle Size Spectrometers

TSI's Particle Size Spectrometers are high resolution sizers that have long been hailed as the researcher's choice for particle size characterization.

Featuring best-in-class size resolution, fast time response, and portability, the TSI family of particle size spectrometers includes an instrument for nearly any application. Particle research and development, atmospheric research, and engine emissions research are just a few of the many applications in which these sizers have become established as the “go-to” instruments for size distribution measurement.
