Abstract：Marine temperature measuring instrument is the most important instrument in marine survey, observation and monitoring business. It needs to carry out measurement calibration to ensure the accuracy and reliability of measurement results, eliminate the systematic error caused by drift. In order to evaluate the consistency of the calibration results of marine temperature measuring instrument among laboratories in different countries, the marine metrology and calibration laboratories of three countries in the Asia Pacific region have carried out the comparison of marine temperature calibration. The results of the comparison are consistent, and the deviation of the measurement results of each reference laboratory is within the acceptable range.
