Lisst SL2


The LISST-SL2 is Sequoia’s most powerful multi-parameter river sediment monitoring instrument. Delivers real-time Point-Integrated, Depth-Integrated, or time-series data.

Replaces old technology samplers.


The streamlined body is a minimum drag shape. In measures depth, velocity, temperature, concentration and size distribution of sediments and other auxiliary parameters. Based on laser diffraction.


The system employs active control of an intake pump that matches intake velocity to river velocity (iso-kinetic).
