Density determination
Density determination of solids can be carried out by means of two pre-defined
types of liquids or user-defined liquid of specified density:
•
WATER
(distilled water),
•
ETHANOL
(spirit 100% +/- 0.1% in temp. 20
0
C),
•
OTHER
(another liquid of specified density).
When 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 carried out 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 same sample
is weighed in liquid, the result of density determination is automatically indicated
on balance display.
In order to determine the density you need to:
•
Install the density determination kit,
•
Enter <DENSITY OF SOLIDS> function
•
Prepare a sample,
•
Initiate the process
•
Insert the settings for the process following the displayed messages,
•
Select liquid in which the determination is carried out
