DENSITY DETERMINATION
The balance can be used to determine an object's density.
Four types of density determination can be made:
• Solids more dense than water
• Solids less dense than water
• Liquid density
• Porous material (impregnated with oil)
A density determination kit is designed to be used
with the balance. Illustrations in this procedure refer
to the density kit. However, you may use whatever
lab apparatus that suits the requirements for density
measurements. The balance software includes a built-in
reference density table for water at temperatures
between 50 ° F and 86 ° F. Review this entire section
before attempting density measurements.
When making density measurements the material
should weigh at least 10 mg on an analytical balance
and 100 mg on a precision balance.
Density can be determined manually (with a key
press after each step) or automatically (weights are
automatically recorded). Before making density
measurements, establish the Application Settings.
