Determining Density Using The Equipment For The Under-Scales Weighing Hanger; Determining Solid Body Density Using The Equipment For The Under-Scales Weighing Hanger - KERN ALJ Operating Manual

12.2 Determining density using the equipment for the under-scales
weighing hanger
Density is the weight [g] to volume [cm
sample in the air. The volume is determined based on the hydrostatic lift [g] of the
sample immersed in a liquid. Density [g/cm
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
precision scales [d] = 0,001 g
precision scales [d] = 0,01 g
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.
Density determination:
 Using the navigation buttons , select the menu item <Density>.
 Confirm by pressing the PRINT button, the current setting will be displayed.
 Using the navigation buttons , select the setting <Solid body>.
 Confirm, pressing PRINT. The present density of the measurement liquid will be
displayed (factory setting 1.0000 for distilled water at 20°C).
