ProdottoSBE-39Plus Temperature (& Pressure) Recorder SBE-39Plus Temperature (& Pressure) Recorder The SBE 39plus is a high-accuracy temperature (pressure optional) recorder with internal battery pack and non-volatile memory for deployment at depths up to 10,500 meters. SBE-39Plus Temperature (& Pressure) RecorderSea-Bird ElectronicsThe SBE 39plus is a high-accuracy temperature (pressure optional) recorder with internal battery pack and non-volatile memory for deployment at depths up to 10,500 meters. The 39plus is intended for moorings or other long-term, fixed-site applications, as well as deployments on nets, towed vehicles, or ROVs. Calibration coefficients are stored in EEPROM, allowing output in decimal or XML ASCII engineering units (raw output available).The thermistor, the same sensor used in the SBE 16plus V2 SeaCAT and 37 MicroCAT, has a long history of exceptional accuracy and stability; drift is typically less than 0.002 °C/year. Two configurations are offered: - Thermistor embedded in titanium end cap (25-sec time constant), for rugged conditions. - External thermistor in pressure-protected sheath (0.5-sec time constant), for fast sampling. The optional strain-gauge pressure sensor is available in eight ranges, from 20 to 7000 m. Compensation of temperature influence on pressure offset and scale is performed by the 39plus' CPU.
