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
0
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.
