Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
TPRL, Inc. has three methods for measuring the thermal expansion of a material.
The push-rod dilatometer is most commonly used. It runs over a temperature
range of liquid nitrogen to 1500°C.
For materials with high expansion (i.e. thin films or bendable solids), the
traveling microscope is used.
For conducting solids, the multi-property apparatus can also
measure thermal expansion. However, since the dilatometer is equally accurate but more economic, it is typically used.

Testing Method Selector Tool to help you decide.
