Thermal Expansion Coefficient Tester

The DIL0809PC Thermal Expansion Coefficient Tester measures the dimensional changes of samples under a specific temperature program and near-zero load conditions. It can test solids, molten metals, powders, coatings, and other sample types, and complies with standards such as ASTM E 831, ASTM D 696, ASTM D 3386, and DIN 51045. This tester studies material characteristics including linear expansion and contraction, glass transition temperature, densification and sintering processes, heat treatment optimization, softening point detection, phase transition processes, effects of additives and raw materials, and reaction kinetics. Our company offers a series of thermal expansion instruments covering a wide temperature range from low to high temperatures, suitable for research, development, and product inspection needs. The accompanying software provides standard measurement and analysis functions, as well as a Rate Controlled Sintering (RCS) option that dynamically optimizes heating rates based on sample shrinkage rates during sintering to maintain a constant shrinkage rate and optimize the sintering process. The product meets ASTM E 831, ASTM D 696, ASTM D 3386, and DIN 51045 standards. The newly developed DIL 0809 PC thermal expansion instrument integrates many advantages: very simple operation, wide application fields, and excellent testing performance. The optimized differential sensor design ensures high reproducibility even without additional constant temperature equipment. The instrument features a horizontal design, which makes the furnace easy to operate and sample loading convenient. Samples of non-ideal sizes can easily fit into the groove of the tubular sample holder. Thermocouples are placed close to the sample to ensure temperature measurement repeatability.
