RBRargo³ C.T.D
Low-power CTD for Argo profiling floats with salinity to the surface; a 2000dbar profile uses only 400J, and the |deep version is rated to 6000dbar.
Description
The RBRargo³ C.T.D is designed for the international Argo program. RBR says it uses 20% of the energy of competing products, and a CFD-optimised flow path reduces salinity spiking.
Key features
- Salinity to the surface as default: the conductivity cell is unaffected by surfactants and is not damaged by drying out
- 2000dbar profile consumes only 400J; sampling up to 8Hz; WOCE accuracy
- Fits standard Argo and NATO A-class float hulls and withstands air deployments
- Integrated on most commercial profiling floats
- BGC sensors available: optical DO, pH, PAR and fluorometers
- RBRargo³ C.T.D|deep6k titanium housing rated to 6000dbar for Deep Argo floats
Applications
Core and Deep Argo profiling floats and other autonomous ocean observing platforms.
