SBE 911plus CTD

The SBE 911plus CTD is the primary oceanographic research tool used by the world’s leading institutions, providing 24 Hz sampling with an SBE 9plus CTD Unit and SBE 11plus V2 Deck Unit.

The 911plus is easily integrated with an SBE 32 Carousel Water Sampler for real-time or autonomous auto-fire operations. The 911plus’ pump-controlled, T-C ducted flow minimizes salinity spiking caused by ship heave and allows for slow descent rates without slowing sensor responses, improving dynamic accuracy and resolving small scale structure in the water column.

The 911plus supports numerous auxiliary sensors (dissolved oxygen, pH, turbidity, fluorescence, oil, PAR, nitrates, altimeter, etc.) with eight A/D channels.
