The accuracy in determination of coefficient of linear expansion of the material of a rod
depends on the precision level of measurement of the expansion produced as a result
of rise in its temperature,
which is provided by a dial gauge indicator, graduated 0.01mm per division.
Ideal for higher grade students.
Dial gauge indicator instead of micrometer, which can be easily assembled into the aparatus or
removed for convenient storage.
It requires no electrical terminals or accessories for measurement.
The apparatus comes completely assembled and includes four expansion rods, one each of
steel, brass, aluminum, and copper.
