Abstract：The comprehensive and detailed uncertainty analysis of the seawater salinity measurement standard based on weight dilution method was studied, especially the transfer relation between the quality and salinity, and the detailed analysis of the components introduced in the process, which provided a detailed technical reference for the improvement of the source traceability and transmission system of the salinity standard value. The results showed that the standard seawater samples prepared by the “weight dilution method” were within the range of 2~35 salinity, and its maximum expansion uncertainty was equivalent to the standard seawater of the first grade in China. The standard seawater samples were tested with the 8400B laboratory salinometer, and the results were fully satisfied with the salt standard equipment.
