✅ Conductivity-Temperature-Depth (CTD) Profiler: It acquires high-precision profile data of seawater temperature, salinity and depth, serving as a core sensing device for marine surveys, marine environmental monitoring and marine engineering investigation.

✅ Multi-parameter Water Quality Monitor: Integrated with multiple water quality sensing modules, it monitors key physicochemical parameters of water bodies in real time and is suitable for long-term online observation in various scenarios such as coastal waters, estuaries, lakes and reservoirs.

✅ In-situ Nutrient Analyzer: It enables in-situ, continuous and automatic detection of nutrients in seawater, supporting research on marine eutrophication, red tide early warning and marine biogeochemistry.

✅ Marine Meteorological Drifting Observer: A lightweight drifting observation platform that simultaneously collects sea surface meteorological and surface oceanographic parameters, suitable for drifting networked observation in open oceans and coastal waters.

✅ Wave Buoy Observer: It monitors wave parameters including wave height, wave period and wave direction at fixed stations over the long term, providing reliable data support for marine disaster prevention and mitigation, offshore engineering and offshore wind farm operation and maintenance.

During the exhibition, the on-site team of Qianhai Technology gave detailed introductions to visiting guests and clients on the technical advantages, performance indicators and typical application cases of each device. In-depth communications were carried out on hot topics such as marine environmental stereoscopic observation, construction of shore-based/offshore monitoring systems, and localization of marine observation equipment. The team listened to market demands and discussed industry-university-research collaboration and potential project cooperation.

Ocean observation serves as the fundamental support for marine governance and the development of a powerful maritime nation. For a long time, Qianhai Technology has focused on the R&D, manufacturing and system integration of marine, hydrological and meteorological environmental observation instruments, continuously delivering stable and reliable sensing equipment and integrated solutions for marine surveys, ecological monitoring, marine disaster prevention and mitigation, offshore new energy and other fields.

This participation in the Fuzhou Marine Equipment Expo marks an in-depth connection between Qianhai Technology and the marine industrial cluster along the southeast coast. Going forward, Qianhai Technology will keep pursuing technological innovation and developing highly reliable, high-precision marine observation equipment. Working together with industry partners, the company will jointly advance the localization and intelligent upgrading of marine observation instruments, safeguarding the blue ocean with the power of sensing.
