12.2 Determining density using the equipment for the under-scales
weighing hanger
Density is the weight [g] to volume [cm
3
] ratio. The weight is obtained by weighing a
sample in the air. The volume is determined based on the hydrostatic lift [g] of the
sample immersed in a liquid. Density [g/cm
3
] of that liquid is known (Archimedes’
principle).
Density is determined using the equipment for the under-scales weighing hanger or a
kit for the density determination.
The optional density determination kit facilitates the density determination:
analytical scales
KERN YDB-03
precision scales [d] = 0,001 g
KERN ALT-A02
precision scales [d] = 0,01 g
KERN PLT-A01
12.2.1 Determining solid body density using the equipment for the
under-scales weighing hanger
Prepare the scale as follows:
• Switch the scale off.
• Turn it upside down carefully.
• Attach the hook for the under-scales weighing (optional).
• Place the scale over an opening.
• Prepare the device for hanging.
• Pour the measurement liquid (e.g. water) in a container (e.g. a beaker) and
obtain a constant temperature.
