Follow this Equipment

Reliable thermal expansion measurements up to 2800°C

The DIL 402 E dilatometer can be operated to 2400°C or 2800°C with the appropriate graphite furnace; optical pyrometers are applied for temperature measurement and control. In this mode, high-temperature resistant samples are tested in glass carbon sample holders under inert atmosphere or vacuum.

Operation to 2000°C is also possible using thermocouples for temperature measurement and control.

Graphite materials, high-temperature ceramics and refractory metals are among the application areas for this versatile, modular high-temperature dilatometer.
