DIL Horizontal Dilatometer | Thermal Expansion Measurement

Horizontal Dilatometer (DIL) | High-Precision Thermal Analysis System

This system is a high-precision horizontal dilatometer (DIL) designed to measure the coefficient of thermal expansion (CTE), phase transition temperatures, sintering behavior, and high-temperature dimensional stability. It is suitable for R&D and quality control of ceramics, metals, composites, and other advanced materials. The L75 PT HS/HD series is specifically developed for academic research and laboratory applications, supporting thermal expansion measurements of solid, powder, and liquid samples.

Frequently Asked Questions (FAQ)

Q: Can the DIL be operated with atmosphere control?
A: Yes. Most models support vacuum and protective gas atmospheres such as nitrogen and argon, making them suitable for sensitive sample measurements.

Q: What sample sizes can be measured?
A: Standard samples are rod-shaped with diameters of Ø6–20 mm. Customized sample holders or push rods can be provided upon request.
