When it comes to determination of the linear thermal expansion in solids, liquids, powders and pastes as well as ceramic fibers, the DIL 402 C vacuum-tight pushrod dilatometer leaves no measurement problem unsolved.
The perfect design of the Invar measurement system with its high-resolution displacement transducer and comprehensive thermostatic control offers the highest degree of accuracy, reproducibility and long-term stability for application temperatures up to 2000°C.

The horizontal design with motorized pushrod and easy to move furnace make it simple to place samples on the special sample supports in the recess of the tube-type sample carrier, even with less than ideal sample geometries. A thermocouple in direct proximity to the sample yields reproducible temperature measurement. This also allows use of the c-DTA® Software for calculation of endothermic and exothermic effects in the sample as well as determination of all the characteristic expansion values.

The interchangeable furnaces with temperature ranges from -180°C to a maximum of 2000°C cover all applications for high-precision expansion control in high-tech ceramic and metallic materials within the scope of material development and basic research as well as quality and production control.
For safe handling of sensitive samples, the DIL 402 C dilatometer can also be supplied in a modified form for installation in a glovebox.
