20.3. Solids Density Determination
Prior the procedure start, it is necessary to set process-related parameters:
−
Liquid type:
o
Distilled water
o
Ethanol
o
Other liquid with determined density
−
Liquid temperature
(required if either distilled water or ethanol is used as liquid for measurement
performance)
−
Liquid density
The parameter is set automatically, after the temperature has been entered, if
either distilled water or ethanol is used as liquid. In case of using liquid other
than distilled water or ethanol, it is necessary to enter its density manually.
The density of solids is calculated using the following formula:
o
B A
A
ρ ρ
−
=
ρ
- density of a sample
A - sample mass measured in the air
B - sample mass measured in liquid
ρ
o
- liquid density
Procedure:
1. Install density determination kit.
2. In order to record density value for a particular product in products database, go to
<Settings> menu, set <Assign density to product> parameter and press <Product>
quick access button to make the product active.
3. Press < Density of solids> button.
4. Respective menu is displayed, using it set the following parameters: Standard liquid,
Temperature, Standard liquid density.
5. Press < START> button.
6. Process of density determination begins.
7. Load the TOP density kit pan with a sample, wait for a stable measurement result and
press < > button.
8. Load the BOTTOM density kit pan (immersed in liquid) with a sample, wait for a stable
measurement result and press < > button.
9. Density result is displayed.
10. Press < > button to complete the procedure.
CAUTION:
Press < > button to start new density determination process with the same settings.
