Liquids Density Determination - RADWAG 4Y Serie Manual Del Usuario

•
Liquid temperature (required if either distilled water or ethanol is used as liquid for
measurement performance)
•
Liquids density (parameter 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:
ρ - density of a sample
A - sample mass measured in the air
B - sample mass measured in liquid
ρ
- liquid density
o
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 <
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.

20.4. Liquids Density Determination

In order to determine density of liquid first determine sinker's density in the air, next in the liquid. The
density of liquid is calculated using the following formula:
ρ - density of liquid
A - sinker mass measured in the air
B - sinker mass measured in water
V - sinker volume
d - air density (max 0.001 g/cm
Install the density determination kit, and enter sinker's volume to balance's memory.
