SBE 3 Temperature and SBE 4 Conductivity Sensors
Modular primary temperature and conductivity sensors used in Sea-Bird CTDs and custom oceanographic systems.
Description
The SBE 4 measures conductivity from 0 to 7 S/m with a frequency output (2.5 to 7.5 kHz) and isolated circuits; the SBE 4C is the primary sensor for the SBE 9plus, 25 and 25plus, and the SBE 4M is for moorings. The SBE 3F temperature sensor, used on the SBE 25/25plus and custom systems, has about 0.07 sec time response, 0.001 °C initial accuracy and typical stability of 0.002 °C/year.
