LISST-100X

Submersible Particle Size Analyzer

Particle Size Distribution Volume Scattering Function Optical Transmission Particle V olume Concentration

The LISST-100X instrument obtains in-situ measurements of particle size distribution, optical transmission, and the optical volume scattering function (VSF). Using a red 670nm diode laser and a custom silicon detector, small-angle scattering from suspended particles is sensed at 32 specific log-spaced angle ranges. This primary measurement is post-processed to obtain sediment size distribution, volume concentration, optical transmission, and VSF. Special versions for deep-ocean use, and for high turbidity environments are available (see LISST-I
