Overview
A controlled atmosphere furnace heats or cools a sample to a target temperature whilst a push-rod transfers the vertical expansion of the sample into a high resolution strain gauge. From this the relative increase in length and the coefficient of thermal expansion (CTE) can be calculated.
Applications
Change in length of solid materials as a function of temperature.
