LISST-100X Series Multi Parameter System - Technical Specifications

The LISST-100X instrument obtains in-situ measurements of particle size distribution, optical transmission, and the optical volume scattering function (VSF). Using a red 670nm diode laser and a custom silicon detector, small-angle scattering from suspended particles is sensed at 32 specific log-spaced angle ranges. This primary measurement is post-processed to obtain sediment size distribution, volume concentration, optical transmission, and VSF. Temperature and depth are also recorded. Optionally, a SeaBird MicroCat 37-SI CTD can be integrated for high precision conductivity, temperature, and depth measurement. Alternatively a Campbell OBS-3+ or a Turner Designs Cyclops-7 fluorometer can be integrated upon request. Special versions with folded housing or a shorter housing with an external battery pack are available. A version for deep-ocean use (LISST-DEEP) is also available. For extended field deployment, our BIOBLOCK anti-fouling system option is recommended.
