The balance can be elevated for suspending specimens in water by means of a Clamp
and Rod Support (see Figure 5).
Figure 5. Specific Gravity Measurements.
A specimen can be suspended from the left-hand platform by tying a string around the
bottom end of the platform support, underneath the base.

To determine specific gravity of solids denser than water, the specimen should be first
weighed in air and then weighed immersed in water.
S. G. = Weight in air
Weight in air minus weight in water

To determine the specific gravity of solids less dense than water, it is necessary to
attach a sinker and then make the following weighings:
a. Weight of body in air
b. Combined weight of body in air plus sinker in water
c. Weight of both body and sinker in water
Specific Gravity = a

ACCESSORY CLAMP & ROD SUP-
PORT Rod fits hole in base of bal-
ance and clamp fastens to table,
desk or bench.
