SeaBird SBE 39 Temperature Recorder
The SBE 39 is a high-accuracy temperature recorder (pressure optional) with internal battery and non-volatile memory for deployment at depths up to 10500 meters. The SBE 39 is intended for moorings or other long-term, fixed-site applications, as well as shorter-term deployments on nets, towed vehicles or ROVs. Calibration coefficients stored in EEPROM allow the SBE 39 to transmit data in engineering units. The SBE 39's thermistor has a long history of exceptional accuracy and stability (typical drift is less than 0.002°C per year). The SBE 39 communicates directly with a computer via a standard RA-232 interface.
