19.1. Determining density of solid object
Before starting the procedure, it is necessary to determine parameters of the
process, such as:
− Type of liquid
o
Distilled water
o
Ethanol
o
Other liquid with determined density
− Liquid temperature
(required if used liquid is distilled water or ethanol)
− Liquid density
It is set automatically if liquid type Water or Ethanol is used and on
inserting liquid temperature. If used liquid is then it has to
be inserted manually.
The density of solids is calculated according to a formula:
o
B A
A
ρ ρ
−
=
ρ - density of a sample
A - sample’s mass measured in the air
B - sample mass measured in liquid
ρ
o
- liquid density
PROCEDURE
1. Assembly the density determination kit
2. Should the density value be saved in a product record of the database of
products, set parameter in and
activate product using quick access key ,
3. Press < Density of solids > soft key
4. A window with menu is opened, set appropriate values for fields: Standard
liquid, Temperature, Density of standard liquid,
5. Press < START > key
6. The balance is ready to start density determining process of solids.
7. Load a sample on the TOP pan of the density kit, and on stabilization of
measurement result press < > key,
8. Load the sample on the BOTTOM pan of the density kit which is immersed
in liquid, and on stabilization of measurement result press < > key,
9. The display indicates result of density determining process,
10. Press < > key to finish the procedure.
