DIL 0809 PC Series Coefficient of Thermal Expansion (CTE) Analyzers

The DIL 0809 PC series measures dimensional change of a sample as a function of temperature or time under a programmed thermal profile with near-zero applied load. It is suitable for solids, molten metals, powders, and coatings, and is widely used across inorganic ceramics, metallic materials, polymer plastics, building materials, coating layers, refractories, and composites. Typical material properties investigated include: linear expansion and shrinkage, glass transition temperature, densification and sintering behavior, heat-treatment optimization, softening point detection, phase transitions, the influence of additives and raw materials, and reaction kinetics. The series spans an exceptionally wide temperature range—from ultra-low to ultra-high temperatures—meeting the needs of R&D and quality control. In addition to standard measurement and analysis, the software provides a Rate-Controlled Sintering (RCS) option that dynamically adjusts the heating rate based on real-time shrinkage rate, enabling constant-rate shrinkage to optimize sintering processes. The instruments comply with ASTM E 831, ASTM D 696, ASTM D 3386, and DIN 51045. The DIL 0809 PC combines ease of operation, broad application coverage, and high measurement performance. An optimized differential sensor design ensures excellent repeatability even without additional temperature-stabilizing equipment. The horizontal instrument layout simplifies furnace handling and sample loading; non-ideal sample geometries can be easily placed into the grooved tubular support. A thermocouple located in close proximity to the sample enhances temperature measurement repeatability. The integrated c-DTA function allows simultaneous detection of endothermic and exothermic effects during CTE testing. Multiple furnace options extend application versatility: −200 to 200 ℃, RT to 500 ℃, RT to 1200 ℃, RT to 1400 ℃, and RT to 1600 ℃. Additional furnace configurations are available separately.
