TSI Particle Instruments are used all over the world in a variety of atmospheric research. These instruments help people understand atmospheric aerosols and their long-term effects on the well-being of our planet.

TSI offers an Integrating Nephelometer that measures the scattering coefficient of aerosols in pristine environments—a key parameter when studying climate, visibility, and air quality. Plus, we manufacture a variety of particle sizers and particle counters that provide reliable atmospheric research measurements. Many of these instruments have been proving themselves for many years, in laboratory and remote settings worldwide.
