摘要: Seawater density has a great importance in the oceanographic science, since it can be used for salinity determination, if is known with necessary accuracy. For that reason, review of methods measurements suitable seawater presented. Furthermore, this work standard measured at different practical salinities (from 9.997 to 37.999) temperature range between (278.15 308.15) K ambient pressure. Measurements are carried out by means vibrating tube densimeter and following substitution method (alternating samples ordinary water). Besides, an accurate analysis uncertainty been performed, obtaining expanded 0.004%. compared results given literature, performed same technique.
