Model SBE 45 MicroTSG, SBE 21 SeaCAT

Underway shipboard thermosalinographs for sea surface temperature and conductivity, with NMEA navigation input and optional SBE 38 remote temperature.

Description

The SBE 45 MicroTSG and SBE 21 SeaCAT are mounted near a ship's seawater intake to measure sea surface temperature and conductivity from underway vessels, with an interface box providing power, isolated data and a NMEA 0183 port for navigation data. An SBE 38 remote sensor at the intake measures temperature with minimal hull contamination.
