Temperature recorder installed with magnets just below water line on inside of ship, providing shipboard determination of sea surface temperature.
The SBE 48 is a high-accuracy temperature recorder with non-volatile memory, designed for shipboard determination of sea surface temperature. Mounted with magnets just below the water line, the SBE 48’s temperature sensor is in contact with the inside of the ship’s hull. The SBE 48’s internal battery runs the real-time clock and can be used to power the instrument for very short deployments; external power is recommended for typical deployments.
Data is recorded in memory and can also be output in real-time in engineering units. Memory capacity exceeds 4.7 million samples of temperature and time; this yields approximately 54 days of data when sampling every 1 sec.
