The SBE 19plus V2 SeaCAT measures conductivity, temperature, and pressure at
4 scans/sec (4 Hz) and provides high accuracy and resolution, reliability, and ease-of-use
for a wide range of research, monitoring, and engineering applications. 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 19plus V2 supports numerous auxiliary sensors (dissolved
oxygen, pH, turbidity, fluorescence, oil, PAR, nitrates, altimeter, etc.) with six A/D channels and
one RS-232 data channel. Data is recorded in memory and can also be output in real-time in
engineering units or raw HEX. Nine alkaline D-cells provide power for up to 60 hours of profiling.
