New Calibration Method for the High-precision and Full-immersion Marine Thermometer

摘要：

According to the changes in temperature and other parameters in the marine environment, we research the measurement accuracy impact factors of the fullimmersion marine thermometer and its calibration method. Through laboratory calibration data of the conductivity, temperature and depth (CTD) instrument to amend the zero and temperature drift of the thermometer. At the same time we compare the thermometer sea-trial data to the MTL (Import) instrument measurement. After the trial and data processing, we get that the temperature error of the full-immersion thermometer is less than 2mK.
