LISST Submersible Particle Size Analyzer

The LISST Submersible Particle Size Analyzer is a water-based, in situ particle analyzer manufactured by Sequoia Scientific. It uses laser diffraction to measure suspended particle size and concentration in aquatic environments, including the ocean, rivers, lakes, and streams. It provides particle size distribution from 1 μm to 500 μm across 36 size ranges. It has a maximum operating depth of 600 m, a resolution of 0.01 m, and a typical sampling rate of 1 Hz. The instrument's laser operates at 670 nm with an optical path of 25 mm.
