SBE 21 SeaCAT Thermosalinograph

The externally powered SBE 21 accurately determines sea surface temperature and conductivity from underway vessels. Data is simultaneously stored in memory and output to a computer in real-time.

Typically mounted near the ship’s seawater intake, the SBE 21 connects to an AC-powered interface box near a computer. The interface box provides power and an isolated data interface, and contains a NMEA 0183 port for appending navigation data.



Memory capacity exceeds 10.6 million samples of temperature and conductivity; real-time output continues after the memory is full.
