With a Dilatometer you can measure the expansion of a sample with a temperature variation.
The expansion signal Delta L or the CTE value (coefficient of thermal expansion) are measured over temperature or time.
The vertical research Dilatometer series L75V is capable of measurements under vacuum, oxidizing and reducing atmospheres (except 2000°C / 2400°C graphite furnace) including ceramics and steel industry applications. The temperature range is 25-1300°C.
