Aquadopp Profiler 2 MHz ADCP

Aquadopp Profiler 2 MHz ADCP

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling range options, from < 1 m to > 85 m.

Description

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in three profiling range options, from < 1 m to > 85 m. The 2 MHz version has a current profiling range of up to 10 m. Designed for simple yet powerful operation, this current profiler is packed with features used by engineers and researchers to enable accurate and effective hydrodynamic data collection in a variety of environmental conditions.

The upgraded Aquadopp Profiler design offers improved noise immunity as well as 6% broadband measurements and “hibernation mode” between measurements, enabling precise data collection with lower power consumption. Increased internal battery storage extends potential deployment time.
