WebThe OBS-3+ uses its sideways-facing optics to emit a near-infrared light into the water. It then measures the light that bounces back from the water’s suspended particles. If an obstruction is in the emitted light’s range, the … Weboptical sensors. A specific WG task was to recommend the most suitable approach for calibrating backscatter and turbidity sensors. This document outlines the Working Group’s recommendation for the most appropriate units with which to calibrate these sensors, and the associated scientific rationale.

WebSeapoint Sensors, Inc. is one of the world's leading manufacturers of underwater optical sensors. Our sensors are known for their high performance, low power consumption, and 6000 meter depth rating.They can be used for in-situ measurements in fresh and salt waters including the most extreme of conditions, and for in-line industrial applications. WebOptical Backscatter Sensor (OBS) An OBS measures turbidity by sending a beam of infrared light into the water and measuring the quantity of light scattered off suspended particles and reflected back to the sensor. Calibration coefficients are then employed to determine suspended sediment concentration. OBS are more sensitive to coarse-grained ...
