Density Determination
Display symbol:
W
Purpose
This application program lets you determine the density of solid substances using the
buoyancy method.
Features
Press
b
to enter the density of the buoyancy liquid* at the corresponding temperature.
See the next page for a table of density values for water. The factory setting is 1 g/cm
2
.
The following formula is applied:
Density of sample =
Weight in air
·
density of liquid
(Weight in air – weight in water)
When you start the density determination routine, the density of the liquid is displayed
briefly. Positive and negative values can be stored for weight in air and weight in water.
The weight in water must be less than the weight in air; otherwise, an error message is
displayed.
You can have results displayed with one, decimal places, or no decimal places:
see “Configuration.” Note: the sample holder and suspension wire used in the example
below are not included with the balance/scale.

When three decimal places are
shown, the third decimal place
might be erroneous; for example,
if corrections for air density and the
particular density determination kit
used are not considered.
