Low-cost acoustic sensor directly measuring Suspended Sediment Concentration (SSC) at a point. Integrates easily with existing dataloggers or monitoring systems. Typical application areas: Environmental monitoring where SSC is of interest, hydropower, sediment studies. Sequoia is in discussion with potential parties that may take over production and are evaluating the technology and market. ...

The LISST-VSF covers the angular range from 0.094 to 150°. Of this, the range 0.094 to 14.9° is covered with Sequoia’s 32-ring detector optics as in the LISST-200X. From 15 to 150° scattering from the length of a laser is viewed by a rotating eyeball. These data produce P12 and a noisy estimate of P22 (no P22 estimate at 45 and ...

The LISST-STOKES from Sequoia is the world’s first commercially available submersible instrument for measuring the depolarization ratio in situ. Temperature and depth is included for each measurement. Also the beam attenuation at the two wavelengths is included with each measurement. Power is applied externally, either via an external power cable or an external battery pack (included). Data ...

The optical Volume Scattering Function(VSF) is an ‘inherent optical property’ of water that is used by optical oceanographers to predict light propagation, image degradation, remote sensed ocean color, biological environment etc. in water. Sequoia offers two instruments for this application. The LISST-200X and LISST-VSF. Respectively, these are for small-angle VSF and full-angle VSF ...
Manufactured by:Sequoia Scientific, Inc. based inBellevue, WASHINGTON (USA)
The LISST-Deep instrument obtains in-situ measurements of particle size distribution, optical transmission, and the optical volume scattering function(VSF) at depths down to 3,000 meters. The LISST-Deep extends operating depth range beyond the LISST-100X or LISST-200X instruments allowing measurements of particle size to be made with at 1 hz with minimal disturbance to the ...

The LISST-Holo2 stores holograms for study of flocs, plankton, and other particles in water. It is an advanced successor of the original LISST-Holo. This new version is the world’s fastest, capturing holograms at 20Hz, [vs.0.2Hz for the original LISST-Holo]. New – the same original housing now includes an 8-hr battery and 250GB of memory. Another powerful new feature ranks thousands ...

FlowControl-Sub is a microprocessor-controlled fully submersible 3-way valve system for use in flow-through applications on profiling platforms such as for example CTD’s or profiling ...
Manufactured by:Sequoia Scientific, Inc. based inBellevue, WASHINGTON (USA)
The LISST-STX is separated into 2 parts when shipping: the main pressure housing (shown on the left) and the settling tube, shipping in a separate box. It is possible to use the LISST-STX without the settling column attached. In this mode it can be used as a LISST-100X. However, due to the difference in the optics end caps of the LISST-100X and the LISST-STX, no accessories designed for the ...

The LISST-Hydro instrument system is designed to supplement Sequoia’s LISST-Infinite instrument in hydro power monitoring applications or work as a standalone instrument for hydro power plants where the sediment concentrations do not exceed 700-8,000 ...
Manufactured by:Sequoia Scientific, Inc. based inBellevue, WASHINGTON (USA)
The LISST-Infinite instrument is designed for use in hydro-power plants to monitor sediment concentration and size distribution for turbine protection. The instrument is installed near intakes, or near draft tubes. The turbid water pressure is reduced to 5 PSI or less and then piped or pumped to the LISST-Infinite. A clean water source is provided for automated dilution. The automated dilution ...

The LISST-SL (for StreamLine) is a laser diffraction system for measuring sediment properties in freshwater rivers and streams. It is not designed for use in brackish or saltwater environments. The streamlined body is a minimum drag shape. Twin fins below the body orient the LISST-SL facing upstream before insertion. A pitot static tube on top of the body measures river velocity. The system ...

The LISST-Portable-XR is the world’s first and only battery powered portable particle size analyzer. It can be used in the field, in the laboratory or on the factory floor. The LISST-Portable|XR analyzes the sample in a wet state to obtain the particle size distribution and the particle volume concentration. The LISST-Portable|XR uses the same laser light scattering method (laser ...
Manufactured by:Hoskin Scientific Limited based inBurnaby, BRITISH COLUMBIA (CANADA)
The first low-cost acoustic backscatter sensor designed specifically for measuring Suspended Sediment Concentration at a point. This is a new type of sediment sensor, superior to turbidity or optical backscatter sensors (OBS) for 4 reasons. See Related Articles in right column. ...
