Sequoia Scientific – LISST-25 Constant Calibration Suspended Sediment Sensor

LISST-25 marks a generational advancement in the measurement of suspended sediments. Unlike all prior sediment sensors, optical or acoustic, the LISST-25 maintains its calibration over a 200:1 range of particle sizes.

Sequoia Scientific – LISST-100 Sediment Size Distribution Sensor

A multi-parameter system for in-situ observations of particle size distribution, optical transmission, pressure and temperature. Special versions are available for deep-ocean, high-concentration, or low-concentration environments. At the heart of the instrument, is a collimated laser diode and a specially constructed annular ring detector.

Sequoia Scientific – LISST-ST Sediment Settling Velocity Sensor

A submersible field instrument developed for in-situ observation of the size-dependent settling velocity distribution of suspended particles. It incorporates a mechanized Settling Column.

Sequoia Scientific – LISST-Portable Particle Size Analyzer

World's first battery powered portable particle analyzer to be used in the field or in the laboratory. Analyzes samples in a wet-state and obtains particle size distribution, and particle volume concentration. Incorporates a mixing chamber with a stirring capability to keep the largest large particles suspended.
