Aquadopp Profiler 1 MHz - 500 m, Generation 2

Small and compact, with up to 25 m current profiling range; option for PUV
wave measurements

The Aquadopp Profiler is a highly versatile Acoustic Doppler Current Profiler (ADCP) available in four profiling
range options, from < 1 m to > 85 m. The 1 MHz version has a current profiling range of up to 25 m. Designed forsimple yet powerful operation, this current profiler is packed with features used by engineers and researchers toenable accurate and effective hydrodynamic data collection in a variety of environmental conditions.
This instrument can also be used to perform river discharge measurements by River Insight.

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