Description

Available as a self-recording current meter, it also integrates unique real-time features to meet your application needs.

The SeaGuardII Acoustic Doppler Profiler, is a smart data hub that combines the SeaGuard electronics with the advanced management firmware of the Aanderaa SmartGuard data hub.

The DCP is a 600kHz frequency profiler with multi-sensor capability for acoustic doppler profiling. By design, we offer increased deployment time, optimized configuration flexibility and unique features to cope with demanding upper ocean environments.

Optional parameters are available using the Aanderaa range of smart sensors, including temperature, pressure, conductivity, oxygen, wave, tide, and turbidity. In addition, the SeaGuardII Profiler has 4 analog inputs, 2 serial ports with power control, and direct connection for real-time data transmission output.
