Since 1995, Sequoia Scientific, Inc. has been the global leader in technologies for submersible and field measurements of particles and particle size distributions. This article shows a few examples where our instruments have been used for various dredging...
The LISST-VSF is the first autonomous VSF instrument for use in the sea. It measures the Volume Scattering Function, the beam attenuation and scattering coefficients (c and b), and depolarization via the elements P12 and P22 of the scattering Mueller...
Upon first impressions the LISST-200X appears to be just a smaller version of the LISST-100X. However much of what makes the LISST-200X such an improvement over the LISST-100X is what lies deep inside the instrument. Let’s explore these features in...
Truly Portable Instrument Reduces Drilling Costs UPDATED 15 AUGUST 2017 The size distribution of drilling muds is frequently adjusted during the drilling process. As such, the particle size distribution must be measured frequently, several times a day....
Last updated: 11 May 2016 Turbidity as a surrogate for suspended sediment concentration (SSC) is commonly used and deeply established in practice. The shortcomings of turbidity as a surrogate for SSC are: The calibration changes with grain size; The...
