Peak performance on thermal expansion measurements up to 2000°C

The highly vacuum tight pushrod dilatometer DIL 402 C will meet all of you measurement needs for determining thermal length changes for solids, melts, powders, pastes,or liquids.  
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.
