Caution:
If in the local parameters, <
is enabled, then on initiating the process, the system asks for inserting
the number of tested sample. The inserted sample number is linked to
the process data and saved in the database.
•
The first phase of the density determination of solid, is measurement
of the solid object in the air. Place the object on the scale's weighing
platform. On obtaining stable measurement result, accept it by
pressing
•
Next, in the auxiliary liquid place scale's weighing platform with
immersed tested solid object. On obtaining stable measurement
result, carry out the measuring process, and accept it by pressing
•
On carrying out the second measurement, the scale determines
density of tested solid and indicates the result on terminal's display.
If the user needs a report from the density determination process,
it can be printed on a plugged printer by pressing
The density determination process is then completed.
•
A report from density determination of solids is saved in <
Density> database. The report is named by process date.
31.3.3. Determining density of pycnometer
Pycnometer- it is a glass vessel which enables precise measurement of liquid
mass at a precisely determined volume. A measurement method applying a
pycnometer is one of the simplest means of determining density of liquids
(densimetric method).
The key component of a pycnometer is a ground-in stopper with dumped
capillary tube, which allows easy observation of the level of liquid contained
in the vessel. Before the measurement process, the pycnometer is
intentionally overfilled with tested liquid, then it is closed tightly with
a stopper and thermally stabilized.
