Equipment | Thermal Analysis |Dilatometers


Dilatometers are used to measure the thermal expansion of a material. By measuring how much a material expands as a function of temperature, the thermal expansion co-efficient can be calculated. The thermal expansion co-efficient (typically expressed in m/m. degrees C) is a useful parameter to know if a material is going to be subject to large temperature variations in its service life. A dilatometer typically consists of a furnace to heat the test sample and a measuring device which may be mechanical or optical in nature.
