DCR - Doppler Current Recorder
The DCR – Doppler Current Recorder is a rugged,
true vector averaging sensor for measuring current speed and direction in water
that employs the same transducer head used in Aanderaa’s RCM-9 current
meters, but adding ease of use and improved capabilities
& versatility to the system.
The DCR
can record data also from the best available sensors from the best manufacturers
in the world for each specific application. When you need to measure parameters
in your moving water with the highest possible quality and reliability, the
DCR is the solution.

The best available
quality for each measured parameter
A DCR with
auxiliary sensors combines all the instruments you might want to deploy in one
single instrument. Data are always perfectly synchronized and are stored in one
single memory.
In one single piece of
equipment you can have RCM9-quality data for single point currents, SeaBird-quality
data for CTD, pH, ORP & DO, Turner-quality data for fluorescence,
Sequoia-quality data for suspended particles, and so on.
