This work aimed to describe the new apparatus of TUBITAK UME for determining the density of liquids at the primary level by means of a hydrostatic weighing (HW) using a solid density standard. This new apparatus provides TUBITAK UME with the necessary infrastructure to certify reference liquids of density with adequate uncertainty to be used at a secondary level. such as for calibrati... https://www.truvisionhealthftp.com/
