Aquadopp Profiler 400 kHz - 500 m, Generation 2

Up to 90 m current profiling range; ideal for mean current measurements

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling
range options, from < 1 m to > 90 m. The 400kHz version is designed for simple yet powerful operation, thiscurrent profiler is packed with features used by engineers and researchers to enable accurate and effectivehydrodynamic data collection in a variety of environmental conditions.

See the details of the Generation 2 Aquadopp updates in the release notes here.
