Integrated Land, Air & Sea Technologies
CTD Instruments
High-precision profiling systems for temperature, conductivity, and depth, from deep-sea hydrographic survey down to shallow coastal and harbor monitoring.
The AbyssPro range delivers rapid, high-accuracy, low-drift CTD data for scientific research and marine engineering, with digital transmission via RS-485, RS-232, and USB.
Three profiler platforms cover the full range of hydrographic survey needs: the AbyssPro7000 for deep-sea CTD profiling, the AbyssPro600 for shallow-water and coastal monitoring, and the AbyssPro TD for dual-parameter temperature-depth observation.
Profiler
Platforms
AbyssPro7000 CTD Profiler
Jointly developed with the Sensor Laboratory of the Institute of Computing Technology, Chinese Academy of Sciences. Novel open-type conductivity sensor design with multi-source data fusion for rapid, high-accuracy, low-drift CTD profiles. MTBF exceeds 50,000 hours.
AbyssPro600 CTD Profiler
Precise complementarity with the AbyssPro7000 series, tailored for scientific research and engineering in nearshore, harbor, and other shallow marine environments, including rivers, oceans, lakes, pipeline networks, and ditches. Ultra-compact for buoys and small submersibles.
AbyssPro TD Profiler
High-precision dual-parameter sensing for temperature and depth, with rapid response and strong drift resistance. Two model variants: RL073A-C (titanium alloy + PEEK, 4,000 m) and RL073A-D (titanium alloy, 7,000 m).
