Intelligent Profiling Measurement
600kHz Doppler profiling, supports broadband and narrowband modes, maximum profiling range up to 80 meters.

High-performance Doppler current profilers (600kHz) for accurate data even in moving/tilted moorings. Two models: standard DCP and DCP Wave (directional wave spectrum, 40m depth). Integrates adaptive acoustics with intelligent data management for simultaneous current profiles, waves, and water quality. Self-recording or real-time. Depth ratings: 300m to 6000m. Ideal for environmental monitoring, engineering surveys, and research.

600kHz Doppler profiling, supports broadband and narrowband modes, maximum profiling range up to 80 meters.
Capable of directional wave spectrum measurement, with wave height range 0.2-20 meters and period 3-30 seconds.
Automatically optimizes transmitted pulses based on sea conditions, improving measurement accuracy and signal-to-noise ratio.
Supports Aanderaa smart sensors and third-party sensors for parameters such as conductivity, temperature, depth, dissolved oxygen, and turbidity.
Advanced tilt compensation algorithm ensures accurate horizontal current data acquisition in dynamic mooring conditions.
Low-power architecture enables 24-month long-term deployment with 30-minute sampling intervals.

Provides baseline environmental data for projects such as offshore wind farms, oil and gas platforms, and submarine cables.
Current field and wave monitoring in ports and waterways to ensure navigation safety.
Research on coastal erosion, sediment transport, wave energy assessment, etc.
Building a regional real-time ocean environmental monitoring network.
Integrated into buoy systems to provide comprehensive marine meteorological data.
Research on ocean physical processes such as current structure, internal waves, and turbulence.
Multi-parameter synchronous monitoring to assess the status of the marine ecological environment.
