LISST-Tau is a high-precision transmissometer for underwater vehicles, profiling packages, CTDs, and other systems. With high-quality optics and a carefully selected LED source, it transmits a collimated beam through the water, and precisely measures the light transmitted through its 15 cm path. Light modulation with synchronous detection rejects ambient light, while oversampling and averaging ...

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 Environmental Remediation Inc. based inCalgary, ALBERTA (CANADA)
Sequoia oxidizers are built with flexibility in mind. Oxidizers can be custom-built specifically for your site requirements, or standard configurations can be purchased in 250, 500, 1000, and 5000 scfm sizes. Our oxidizers can use all types of make-up fuels, including natural gas, propane, diesel, and waste fuel from oil fields ...

Disposal of waste water can be costly for many utilities, oil & gas fields, refineries and recyclers. Some wastewaters contain high total dissolved solids (TDS) including chlorides. Some others are distilled over in process units or dropped out in the bottom of tank and contain suspended solids, near-boilers like glycols and also toxics like volatiles organics or ...
Manufactured by:Sequoia Global, Inc. based inCarson City, NEVADA (USA)
Sequoia’s process technology for coolant (antifreeze) recycling is based on vacuum distillation. It produces distilled water and >95% pure glycols from waste coolants. Approximately 3-10% residue is produced. The residue contains trace amount of oil, spent additives and sludge present in the spent ...
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-HAB is a self-contained, stand-alone instrument system for use on profiling packages, towed and remote vehicle applications, for deployment during a HAB event. The system will continuously measure particle size distribution and concentration, along with the fluorescence of Phycocyanin (Freshwater HAB’s), Phycoerythrin (Marine HAB’s), Chlorophyll and beam ...

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 ...
