Density determination of liquids

Basic element for determining density of liquids is a glass sinker with

precisely determined volume. Before starting liquid density determination,

insert the value of sinker’s volume to balance memory. In order to measure

the density of liquid, first determine mass of the sinker in the air. Then

measure mass of the same sinker in tested liquid.

Procedure

•

Press

Mode

key, then using navigating arrows go to submenu

F7 d_Li

•

Insert sinker’s volume that is specified on its hook
