ADCP-75-SC-PA4
Designed specifically for moored current profile measurement applications
Key Features:Self-contained ADCP 75k
Battery-Powered Unattended Deep-Sea Operation
Built-in alkaline battery enables long-term, cable-free deployment for fixed-point deep-water monitoring. No external power required, ideal for remote offshore and open-ocean sites.
Ultra-Long Deep-Sea Profiling Range
Designed for deep-ocean applications, offering a maximum profiling range of 650 m (narrowband) / 550 m (broadband), with bottom tracking capability up to 1000 m for reliable data in deep water.
Reliable High-Precision Flow Measurement
Delivers consistent velocity profiling with ±1.0% ±5 mm/s accuracy and 1 mm/s resolution, paired with 0–360° directional sensing at ±2° precision, suitable for demanding oceanographic research and engineering monitoring.
Customizable Deep-Water Profiling 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.
Rugged Titanium Alloy Deep-Sea Housing
Built with corrosion-resistant titanium alloy, available in 1500 m, 3000 m, and 6000 m pressure-rated configurations, ensuring durability in high-pressure deep-sea environments.
Integrated Environmental & Attitude Sensors
Equipped with precision temperature, pressure, and attitude (roll/pitch/heading) sensors to maintain data accuracy under harsh, variable marine conditions.
Large On-Board Storage & Connectivity
64 GB Micro SD memory supports long-duration data logging, with RS-232/RS-422 interfaces for reliable data retrieval and integration with field systems.
Optimized Power Efficiency for Long Deployments
Average power consumption ≤ 20 W maximizes battery life, enabling extended unattended missions in remote offshore and deep-sea locations.
