New release of LISST-ABS software v2.1 – improved LISST-AOBS capability! To accommodate the growing number of LISST-AOBS customers, the LISST-ABS software now also handles LISST-AOBS data. The LISST-ABS software v2.1 will now connect to a LISST-ABS...
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 USGS has evaluated Sequoia’s LISST-ABS at 10 streamflow-gaging stations, collecting LISST-ABS and suspended sediment concentration (SSC) data between January 2016 and February 2018. The evaluation also compared the LISST-ABS to standard turbidity...
Earlier this month, Sequoia sent out a survey to our LISST-ABS users to get feedback on how we can continue to improve this instrument. Survey participants were entered into a drawing for $200. Our winner was Cindy Crane from the Prince Edward Island...
The short explanation Briefly, the difference between turbidity and Super-Turbidity (Patent Pending) can be summarized as follows: Turbidity (NTU) = Optical Backscatter; Needs Calibration for SSC; less accurate Super-Turbidity (mg/l) = Optical & Acoustic...
