Product Description
The system determines the temperature associated with specified specimen deformation during simultaneous heating and loading. Differential and non-differential test configurations are available for ceramic refractory and graphite materials.
Heating may be manually controlled or automatically programmed with at least 30 segments. The system has an openable furnace, an independent loading system, digital load display, a computer interface, and automatic test-report printing.
Ordering information: Specify the differential or non-differential method, furnace-temperature option, specimen geometry, applied-pressure and load-range configuration, and required control and reporting options when requesting a quotation.
