CTDs for Argo floats
Ultra low power, compact design
To assist with the international Argo program, we developed the RBRargo³ C.T.D for profiling floats. Salinity to the surface is default behaviour: the conductivity cell is unaffected by surfactants and is not damaged by drying out. A full range of additional sensors is available, including optical dissolved oxygen, pH, PAR, fluorometers, and others.
Our RBRargo³ C.T.D has been integrated and tested on most commercial profiling floats.
RBRargo³ C.T.D: multi-channel instrument for profiling floats
Features
- Rated to 2000dbar (higher depth ratings available)
- WOCE accuracy
- 2000dbar profile consumes only 400J
- Accurate conductivity to within 10cm of the air-ocean interface
- Flushing by design – no pump required
- Up to 8Hz sampling
- Streamlined design minimizes salinity spiking

Available sensors:
Conductivity (C), Temperature (T), Pressure (D), Optical Dissolved Oxygen (ODO), Photosynthetically Active Radiation (PAR), Radiometer (rad), Turbidity (Tu), Backscatter (bb), Fluorescence (Fl), pH, Voltage
