Nortek Signature 55: ADCP

Availability: , ,

The Nortek Signature 55 ADCP is a long range dual-frequency current profiler. It utilises broadband processing and the latest electronics for flexible measurement of the water movement, such as waves and for currents too.


Broadband combines the frequency-modulated transmissions with fast sampling rates and adjusted bandwidth.

Ethernet connection provides easy access to the instrument from any location, simple integration into instrumentation networks, and fast recorder download.

AD2CP hardware can alternate between multiple measurement modes.

Adjustable power output facilitates long endurance operation by allowing new short-range applications, which combine higher vertical resolution with lower power consumption.

AD2CP recorders will store all raw Doppler and sensor data. Improve data quality by removing contamination from fish or other influences.
