12 Density determination
When measuring the density of solids, the solid is first weighed in air and then in an
auxiliary liquid whose density is known. From the weight difference results the
buoyancy from where the software calculates the density.
As auxiliary liquid mostly distilled water or ethanol are used, densitiy tables see chap.
12.1.
The following steps must be followed to measure the density:
1. Prepare the measuring equipment
2. Select weighing application for density determination
3. Select medium
4. Set water temperature or specific density
5. Weigh sample by underfloorweighing
6. Correction of residual errors due to immersion basket
7. Measure sample
• After completing the underfloor weighing the opening on the bottom
of the balance must always be closed (dust protection).
• The immersion basket must not come into contact with the container
• The hook for the underfloor weighing is available as optional
accessory
