Dilatometer / DIL 402 Expedis Supreme
A dilatometer measures the change of a sample length Δl temperature dependently. Thus, it provides information on the thermal expansion of a material, phase transitions and sintering properties.
The laboratory includes a DIL 402 Expedis Supreme (NETZSCH-Gerätebau GmbH), which is a push rod dilatometer with controlled and adjustable contact force. Two furnaces are available in order to reach temperatures below room temperature and well above room temperature.
