Dual- and differential-dilatometer unified in a new concept

Are higher sample throughput, direct comparison of samples, and online calibration of expansion measurements important requirements for you? With the new dilatometer DIL 402 CD we handle these tasks perfectly with our unique, new instrument concept.

The measuring system employs two high resolution inductive displacement transducers; with its design using low-expansion invar and broad thermostatic control for highest accuracy, reproducibility and long term stability, it is capable of application temperatures up to 1600°C

The horizontal instrument construction offers specific advantages, especially for the dual sample arrangement: homogeneous heating of both samples, simple sample insertion, safety during sample decomposition or melting, and effective protection of the measuring system by gas flow. The operation remains simple and safe through exact sample arrangement at the specific sample support in the cutout of the tube sample support, the individual motorized movement and zero setting of both push rods and the easy to move furnace. Various furnace systems allow optimal adjustment at specific measuring tasks.

The sample temperature measurement is carried out reproducibly with a thermocouple in
the center of the sample arrangement.

Routine measurements with high sample throughput and accurate comparison measurements
are two further important application fields of this new dual- and differential dilatometer.
