Optical Dilatometry Platform HM 867 from TA Instruments is a stand-alone heating microscope that is a standard instrument for process optimization in the ceramics sector. It is the most innovative tool for production and R&D laboratories for the optimization of all industrial processes containing thermal cycles.
A single camera on the optical bench frames the total sample and records the sequence of the characteristic shape variations and the temperature throughout the experiment. This is suitable for identifying all major material change events including softening, sintering, half-sphere, full sphere and melting. Dimension variations up to 100% can be measured.
With a maximum temperature scanning rate of 80 °C/minute, it has a built-in purge gas system that enables the user to test specimens in reductive, oxidative, air 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.
