Sequoia LISST-AOBS Super-Turbidity Sensor

The Sequoia LISST-AOBS is a simple, low-cost Super-Turbidity sensor to measure suspended sediment concentration (SSC; mg/l) and turbidity (V).

Features

• Paired acoustic and optical technologies
• Near-constant calibration within a factor of two for grain-sizes from 1–500 µm
• Includes Y-cable providing power and integrated SDI-12 communication to and from both sensors

Details

Overview
The Sequoia LISST-AOBS is a simple, low-cost Super-Turbidity sensor that measures suspended sediment concentration (SSC; mg/l) and turbidity (V). The Sequoia Super-Turbidity sensor 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.

Connectivity
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. The Sequoia Super-Turbidity sensor includes a Y-cable providing power and integrated SDI-12 communication to and from both sensors.
