The deep-sea CDOM sensor is based on fluorescence measurement technology. It utilizes an ultraviolet light source to excite chromophoric dissolved organic matter CDOM in the ocean, causing it to emit fluorescence signals within specific wavelength bands. By detecting changes in fluorescence intensity, the sensor achieves precise inversion of CDOM concentration. With technical advantages such as high detection sensitivity and fast response speed, it is compatible with mobile observation platforms like Argo floats and underwater gliders, as well as fixed monitoring equipment such as moorings and shipboard water samplers. This enables multidimensional and high-precision observation of CDOM concentration in deep-sea profiles, providing crucial technical support for marine carbon cycle research and ecological environment monitoring.

The shallow-water CDOM sensor operates on the principle of fluorescence measurement technology. It utilizes an ultraviolet light source to excite chromophoric dissolved organic matter (CDOM) in seawater, causing it to emit fluorescence signals within specific wavelength bands. By detecting variations in fluorescence intensity, the sensor enables accurate inversion of CDOM concentration. The sensor can be optionally equipped with a wiper device to effectively prevent biofouling, ensuring long-term monitoring reliability. Featuring high detection sensitivity and rapid response time among other technical advantages, it is compatible with mobile observation platforms such as Argo floats and underwater gliders, as well as fixed monitoring equipment like moored buoys and shipboard water samplers. This allows for multidimensional and high-precision observation of CDOM concentration in shallow-water profiles, providing critical technical support for research on marine carbon cycles and ecological environment monitoring.

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.

The shallow water turbidity sensor operates on the principle of light scattering measurement. It consists of an excitation light source (LED), a photodiode, and a signal processing module, enabling simultaneous detection of water turbidity and temperature parameters. This sensor can be optionally equipped with a mechanical wiper anti-fouling device, effectively addressing biological contamination issues. It offers excellent long-term stability and can operate continuously for months in unattended environments without requiring maintenance. The product meets monitoring requirements for various water environments such as rivers, lakes, oceans, and groundwater. It can be used independently or integrated as a multi-parameter sensor into mobile or fixed monitoring platforms including shore-based stations, shipboard equipment, buoys. It is widely applied in fields such as marine surveys, ecological environment monitoring, and aquaculture.
