The deep-sea turbidity sensor operates based on the light scattering measurement principle, detecting the scattering intensity of near-infrared light by suspended particles in water to measure turbidity. This sensor features high sensitivity, rapid response, compact size, and lightweight design, making it easy to integrate into systems and maintain. It is compatible with mobile observation platforms such as Argo floats and underwater gliders, as well as fixed monitoring equipment like moorings and shipboard water samplers, enabling high-precision continuous observation of deep-sea turbidity.
