4. Density measurement
The balance is capable of measuring the density of either a solid or a liquid. The balance
can be used with the Adam Equipment Density Determination Kit as described below or by
using the weigh below abilities of the balance.
4.1 Density Measurement of Solids
To determine the density of a solid it is necessary to weigh the sample while in the air and
then to weigh it while it is suspended in a liquid of known density. The balance will guide you
through the steps of this procedure using messages on the display. The type of liquid that
can be used are set by the user. It includes distilled water, alcohol and any other liquid as
long as the user knows its density.
•
WATER (distilled water)
•
ALCOHOL (spirit 100% +/- 0.1% in temperature 20
0
C),
•
OTHER (a user supplied liquid with known density)
For water and alcohol you will be required to give the temperature, therefore the thermometer
is included in the kit.
Density checking relays on weighing a sample in the air and then in the liquid.
Result of the test is shown on the display automatically when the test if finished.
Result of measurement can be sent over the RS 232 interface to a printer or PC by
pressing the Print key.
