Designed by Sequoia’s engineering team, the all new LISST-Tau is a high precision transmissometer for use on underwater vehicles, profiling platforms, CTD’s and other underwater sampling systems. The LISST-Tau precisely measures optical transmission and beam attenuation at depths down to 2,000 meters. https://lnkd.in/dFfs2BEJ #LISST #Transmissometer #environmentalimpact #environmentalsustainability #environmentalengineering #engineering #research #oceanscience #environmentalmonitoring #animation #video #howthingswork

Sequoia designs and manufactures the LISST series of laser, acoustic and holographic sensors used worldwide since 1995.
About us
Since 1995, Sequoia Scientific, Inc. has been the global leader in technologies for submersible and field measurements of suspended particles, and particle size distributions. Sequoia invented the LISST series of aquatic science sensors in 1995. Since then, more than 40 different types of sensors have been developed, prototyped, or manufactured by Sequoia. Today, thousands of Sequoia instruments are in use, helping ocean and freshwater scientists and managers around the world better understand our oceans and the aquatic environment. All design and production takes place in our Bellevue, WA location. Our sales staff is located in Bellevue, WA and Mobile, AL. LISST was originally an acronym for our laser particle sizing sensors (Laser In Situ Scattering and Transmissometry). LISST now is ‘just’ a Sequoia trade name. Most of our instruments still use lasers in one way or the other to make measurements. A few use LED’s or acoustics. Sometimes two methodologies are used together. Several of our instruments measure the in-situ size and/or concentration of suspended particles – sediment grains, algae, flocs, oil droplets, air bubbles, aeolian sediment, drilling fluids etc. One model takes pretty particle pictures using holography. Others again measure water optical properties such as beam attenuation, Volume Scattering Function (VSF), and hyperspectral backscatter. The instruments are primarily used for ocean science and freshwater research and for environmental monitoring. However, some are used in select industries in a range of drilling fluid, hydropower, and general process control applications. How do you know if you need a LISST? Are you an oceanographer, limnologist, biogeochemist, geographer, geologist, soil scientist or coastal, environmental, consulting or drilling engineer? Or do you have an interest in (suspended) particle measurements or the optical properties of water? Or do you work in Industrial Process? Then we most likely have an instrument for you.

Sequoia instruments are used in drilling operations worldwide! The technology is commonly used to accurately monitor size changes to particles found in drilling fluids. The LISST-Portable|XR product allows analysis of particle size distribution and concentration data during the active drilling process, completed at the rig and often under rugged environmental conditions. Dependable real-time data is critical and allows operators to see anomalies in the distribution curve which may indicate a failure or alert them to take-action if a threshold is crossed. Using industry proven laser diffraction secured inside an impact resistant enclosure, the LISST-Portable|XR allows operators to obtain lab quality data in the field, learn more here: https://lnkd.in/grtxadg Truly Portable Instrument Reduces Drilling Costs: https://lnkd.in/dbt8PqAC LISST-Portable|XR now with x100+ faster processing: https://lnkd.in/dbj97qbK LISST-Portable|XR Comparison with Beckman Coulter, Cilas, and Malvern Particle Sizers: https://lnkd.in/drQyiCyE #LISST #OFITE

Sequoia instruments measure IOP’s. What are they and why are they so critically important? IOP stands for ‘inherent optical property’—‘inherent’ in that they depend only upon the medium, for example, seawater including the dissolved and suspended materials within it. Two fundamental IOPs are the absorption coefficient and the volume scattering function (VSF). A third IOP often considered in oceanography is the beam attenuation coefficient, which is the sum of the absorption and total scattering coefficients. IOPs are independent of the ambient light field, for example, the position of the Sun; and are usually measured with ‘active’ sensors, meaning that they use a light source and detect how that light is affected by the medium. This independence allows IOPs to be measured across various platforms ranging from conventional moorings and marine vessels to remotely operated vehicles such as autonomous profilers and gliders. IOPs provide a means to quantify characteristics of in-water constituents such as phytoplankton and sediments to better understand water quality. They also provide a critical connection between the characteristic components in the seawater and the signal seen by ocean color satellites. Sequoia currently empowers scientists worldwide with multiple instruments for measuring IOPs in support of water quality and ocean color research: · LISST-200X and LISST-Deep Submersible Particle Size Analyzers measure beam attenuation in addition to particle size distribution · LISST-Tau High-Precision Transmissometer · Hyper-a Hyperspectral Absorption Instrument · Hyper-bb Hyperspectral Backscatter Instrument · LISST-VSF Multi-Angle Polarized Light Scattering Instrument Learn more here: https://lnkd.in/gykXrFqT #LISST #RemoteSensingReflectance
