  • High Performance Dilatometers Brochure


Dilatometry is a method for measuring changes in a sample’s size as it’s heated or cooled. It can provide information about phase transitions and changes in the sample’s structure.

The TA Instruments dilatometers, including DIL806 and ODP868, use an optical measurement method to evaluate the shadow width of a sample placed horizontally inside a furnace. This method is free of external contact forces, making it ideal for measuring soft, fragile, or small samples that may be damaged or difficult to handle in a pushrod dilatometer.

The DIL806 can measure samples in various atmospheres and cover temperatures from -150°C to 1400°C. The ODP868 can analyze samples’ dimensions, shape, and bending up to 1650°C. Optical dilatometry offers high resolution and accuracy similar to a pushrod dilatometer, making it an optimal method for measuring challenging samples.

Available Models

The Optical Dilatometry Platform HM 867 is a stand-alone Heating Microscope that is a standard instrument for process optimization in the ceramics industry. A single camera on the optical bench frames the entire sample and records the sequence of the characteristic shape changes and the temperature throughout the experiment. This is ideal for identifying all key material change events including sintering, softening, full sphere, half-sphere, and melting. Dimension changes up to 100% can be measured. With a maximum temperature scanning rate of 80°C/min, it has a built-in purge gas system that enables the user to test specimens in air, oxidative, reductive and protective atmospheres. The heating microscope is available as a standalone instrument, HM 867, or as an option on the Optical Dilatometry Platform, ODP 868.

The ODP 868 platform can be configured in the following operational modes that will suit your applications.

The ODP 868 is the culmination of over two decades of research and development in optical instruments for studying materials’ thermo-mechanical behavior. With this innovative tool, your production and R&D laboratories can optimize all industrial processes involving thermal cycles.

Unlike classical heating microscopy, the ODP 868 can analyze a wide range of sample shapes and sizes. It can simultaneously analyze up to 8 samples of ISO standard size, including a 3mm sample and a 10mm sample. Additionally, the tool’s Heating Microscope mode uses a 5Mpix high-resolution camera to study materials’ physical behavior during firing cycles. This feature enables you to study and better understand how materials react to heat and thermal cycles.

One of the ODP 868’s most unique features is the Morphometrics applicative, which automatically calculates and visualizes different characteristic temperatures and parameters in real time during analysis. This feature allows you to make informed decisions about optimizing industrial processes for improved product quality, reduced costs, and increased efficiency.

The DIL 806 dilatometer is an invaluable tool for analyzing materials’ thermal expansion in a range of industrial applications. Its unique optical measurement method provides accurate and absolute measurements of the sample’s dimension with changing temperature, making it a reliable and accurate tool for analyzing materials’ thermal expansion. The shadowed light method is independent of any expansion or contraction of the instrument, eliminating the need for correction or calibration of results for different temperature programs. The furnace can rapidly heat up to 100°C/min and cool from 1400°C to 50°C in under 10 minutes, allowing for the analysis of dynamic processes involving multiple temperature steps and heating rates. Thin samples can also be analyzed easily with the sample holder specifically designed for this purpose.

The DIL 806 dilatometer is particularly well-suited for analyzing metals and plastics, with the optional sub-zero furnace expanding its capabilities even further. The sample is positioned on a platform in the center of the disc-shaped furnace, which is not subjected to external forces. This makes it ideal for measuring samples of different shapes and sizes. The broad width of the incident light simplifies sample preparation and improves usability, even for inexperienced operators. The initial length is automatically determined and saved for calculating the linear thermal expansion coefficient.

Overall, the DIL 806 dilatometer is a valuable tool for analyzing materials’ thermal expansion and optimizing industrial processes.
