DIL-Q Quenching Deformation Dilatometer

The quenching deformation dilatometer is designed to test the coefficient of thermal expansion of metallic materials, ceramics, refractories, and other solid materials by using the expansion method in phase transformation analysis.

It is particularly applied to corundum, refractory materials, precision mold shells, and core-type materials in the determination of critical temperatures and phase transformation analysis. The instrument is capable of performing coefficient of thermal expansion (CTE) tests, material phase transition temperature (TTT) tests, and continuous cooling transformation (CCT) tests. It provides the required testing methods for factories, scientific academies, and in the fields of material property testing, research, and education.
