The LISST-STX is DISCONTINUED.
As of July 2019, Sequoia can and will still service and support existing LISST-STX instruments. However, Sequoia does not manufacture new LISST-STX instruments.
The LISST-STX is a submersible field instrument developed for in-situ observation of the size-dependent settling velocity distribution of suspended particles. It incorporates a mechanized Settling Column.
The LISST-STX is designed to carry out multiple settling experiments while submerged. A motorized mechanism operates the doors that control exchange of water between the settling column and the ambient environment. This permits repeated settling experiments.
A separate built-in motorized stirrer is used to agitate and flush out settled particles after each settling experiment.
