Aquadopp Profiler 2

400 kHz

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

  • Up to 90 m current profiling range
  • Ideal for mean current measurements
  • Easy to operate and deploy


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, 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.

  • Currents


  • Up to 90 m current profiling range
  • Ideal for mean current measurements
  • Easy to operate and deploy


  • Mean flow measurements with high focus on ease of use and simplicity
  • Measurements in flow regimes with strong variations in flow speeds
  • Studies of tidal currents
  • Suitable for wave buoys


The 400kHz Aquadopp Profiler, designed for straightforward current measurements at up to a 90m range, is set up using the Nortek deployment software, enabling users to customize measurement schemes and assess power requirements. It offers the longest profiling range of the Aquadopp Profiler family.


Teams of all sizes can deploy an Aquadopp Profiler successfully thanks to its compact size and flexible deployment options. Buoy, bottom frame and inline setups from Nortek and leading industry partners are available specifically for the instrument.


Nortek postprocessing software and/or display software is available for review, visualization, and processing of data, after deployment or in real time.
