Nortek Signature55 ADCP

Okeanus by 

The Nortek Signature55 dual frequency long range current profiler was designed to operate at both 55 and 75 kHz, with a range of up to 1000m in open water. Utilizing true broadband AD2CP technology, sampling schemes can be set up to alternate between these two operating frequencies to minimize power consumption depending upon range, resolution, and deployment duration. Because of the unit’s compact size, operational deployment is made easier and more cost effective for the end user. The Signature55 is designed to be mounted on surface or subsurface buoys, bottom frames or offshore platforms.


  • AD2CP broadband for rapid sampling
  • Alternation between measurement frequencies
  • Ethernet connection for simplified setup and fast data downloads
  • 1000m range
