LISST-AOBS Super-Turbidity Sensor

Super-Turbidity Sensor

The LISST-AOBS Super-Turbidity sensor is a sensor to measure suspended sediment concentration (SSC).

See a list of papers published with LISST-AOBS data here!

Super-Turbidity involves pairing a LISST-ABS with a turbidity sensor using a weight factor, which results in a single, combined output from the two sensors. Once paired, the LISST-AOBS retains near-constant calibration for SSC over a wide grain-size range. The LISST-AOBS Super-Turbidity sensor is supplied by Sequoia as an integrated and paired turbidity and acoustic sensor with a variety of cabling and data logger options.

NOTE: The LISST-AOBS will be discontinued from 31st March 2025. Read our discontinuation notice here.

UPDATE 4/16/2025: Sequoia is in discussion with potential parties that may take over production and are evaluating the technology and market. Sequoia will continue production until a decision has been made in this regard. U nits are in stock for immediate delivery and Sequoia is still taking orders.
