Additional information

This multipurpose particle spectrometer is five instruments packaged into a single, integrated measurement system that provides aerosol particle and cloud hydrometeor size distributions from 0.5 to 50µm, particle shape (discrimination between water and ice), particle optical properties (refractive index), precipitation size distributions from 25µm to 1550µm, liquid water content from 0.01 to 3 g/m3 and aircraft velocity and atmospheric temperature and pressure.
This instrument replaces PMS Inc.'s FSSP-100, FSSP-300, 2D-C, 2D-P and KLWC and can be used in many applications, including weather modification,
aircraft icing, hurricane and storm research, and agricultural and industrial spray characterization.
