Deep-Sea Profiling Capability
Designed for open and deep-sea applications, offering an ultra-long profiling range (up to 650 m narrowband / 550 m broadband) and bottom tracking up to 1000 m, enabling reliable current measurement in deep-water environments.
Reliable High-Precision Flow Measurement
Delivers consistent velocity profiling with ±1.0% ±5 mm/s accuracy and 1 mm/s resolution, supporting 0–360° directional sensing with ±2° precision, ideal for demanding oceanographic research and engineering monitoring.
Customizable Vertical Resolution
Flexible cell layer thickness from 4 m to 32 m, combined with up to 255 measurement layers, allowing users to balance range and resolution for deep-ocean current studies.
Stable & Rugged Deep-Sea Design
Built with corrosion-resistant titanium alloy housing, available in 1500 m, 3000 m, and 6000 m pressure-rated configurations, ensuring durability in high-pressure deep-sea conditions.
High-Reliability Environmental Compensation
Integrated precision temperature, pressure, and attitude sensors (roll/pitch/heading) ensure stable performance and accurate data even in harsh, dynamic marine environments.
Real-Time Data Acquisition
Supports 1 Hz data update rate (without bottom tracking) and 0.5 Hz (with bottom tracking), enabling responsive, real-time monitoring for offshore engineering and ocean science missions.
Flexible Data Storage & Communication
Equipped with 64 GB on-board Micro SD storage and RS-232/RS-422 interfaces, providing reliable data logging and seamless integration with field systems and data platforms.
Deep-Sea Ready Power & Operation
Average power consumption ≤ 20 W, with wide input voltage support (20–50 V) and a rugged power interface, optimized for deep-water installations and long-duration field deployments.
