LISST Submersible Particle Size Analyzer

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