Integrating Nephelometers are analytical instruments useful for short-or long-term measurements of the light-scattering coefficient of atmospheric and laboratory aerosols. They are particularly well-suited for measurements related to climate, visibility, and air quality.

These unique instruments offer sensitivity to aerosol-scattering coefficients lower than 2.0 x 10-7 meter-1. That's as much as two orders of magnitude better than other commercial instruments!

TSI offers versions with one or three wavelengths. The three-color model allows measurement of total and backscatter signals. Both Integrating Nephelometers operate under complete computer control.
