Dilatometer / Dilatometry (DIL)

Dilatometry (DIL) measures volume changes caused by physical and chemical processes. They are used in manufacturing, engineering, materials science, and chemistry labs. When working with a dilatometer, the first step is to load the sample into the machine. The sample is subjected to physical or chemical processes, most often in the form of heating from a furnace, and a sensor picks up on the volume changes.

Dilatometers can be used to calculate a material's coefficient of thermal expansion, softening point, glass transition temperature, Curie point, crystalline transformation, phase transition, and amount of shrinkage. When purchasing dilatometry equipment, it is important to consider the type of material that will be tested, the method of capture for measurements, and the software used.

Suitable for a wide range of routine dilatometric tests, the DIL 801 and DIL 801L are horizontally configured single-sample dilatometers. The DIL 801 is designed for measurements under vacuum or inert gas while the

Two-samples simultaneous operation to maximize productivity without comprises on results.

To maximize sample throughput, DIL 803 and DIL 803L offers two-samples simultaneous operation. DIL803 and DIL 803L can also be operated with an inert reference sample for quasi-differential measurement, reducing

This optical dilatometric measurement method used in DIL 806 is an absolute process, entirely independent of any possible expansion or contraction of the instrument. Consequently, measured results do not need to be corrected or calibrated for different temperature programs. Coupled with the fast Result of over twenty years of R&D of optical instruments for the study of the thermo-mechanical behavior of materials, HM 867 makes possible the analysis of samples beyond the limits of classical heating microscopy. Its versatility makes of HM 867 the most innovative tool for both R&D and for the ... Read More
