14.5.1. Testing thickness solids

Density determination of solids can be conducted in two pre-defined types

of liquids or user-defined liquid with specified density:

• H2O (distilled water),

• C2H5OH (spirit 100% +/- 0.1% in temp. 20

C),

• AnotHEr (another liquid with specified density)

In case of determining density in water or alcohol it is necessary to specify

their temperature. For another liquid, its value (density) is inserted from

balance keyboard. Density determination is conducted by weighing a

sample first in the air (top weighing pan (4) of the density kit), and then

weighing the same sample in liquid (on the bottom weighing pan (2) of the

density kit). As the sample is weighed in liquid, the result of density

determination is automatically indicated on balance display.

14.5.2. Testing thickness of liquid

Basic element for determining density of liquids is a glass sinker (9). Its

volume is precisely determined and given on sinker’s hanger. 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. The result of liquid density determination is automatically

indicated on balance display.
