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.

DescriptionResult of over twenty years of R&D of optical instruments for the study of the thermo-mechanical behavior of materials, ODP 868 makes possible the analysis of samples beyond the limits of classical heating microscopy. Its versatility makes of ODP 868 the most innovative tool for production and R&D ... Read MoreTwo-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

The DIL805 Series comprises of four models: DIL 805L, DIL 805A are quenching dilatometers, DIL 805A/D is a quenching with the capability to deform the specimen by compression, and DIL 805A/D/T that can also stretch it in tension mode.

All four instruments are fully automated, self-contained units

The 820 Series operate in a vertical orientation, making it uniquely set up for the analysis of sintering, studies in Rate Controlled Sintering (RCS) mode and the determination of dilatometric parameters of samples otherwise difficult to be analyzed on classic dilatometers with horizontal design.

Based upon the double beam design, with one optical path always aligned to the top of the specimen while the second focused on sample lower end correcting for any thermal-profile related drift, the contact-less Vertical Optical Dilatometer Misura® 3 ODHT allows to carry out measurements of ...
