UNITHERM™ 1000 SERIES ULTRA-DILATOMETERS

This instrument is a fully computerized high precision dilatometer system designed to measure dimensional changes of a specimen brought about by changes in its thermal environment. Linear thermal expansion coefficient, annealing characteristics and other physical or chemical changes manifesting themselves in a change of linear dimension can be precisely determined. Studies of processing parameters as reflected by dimensional changes of the material can be studied in great detail through duplication of thermal cycles and rates used in the actual process. Due to the flexible programming of thermal cycles, complex processes can be easily simulated.

[70] Computer, printer, monitor The digital displacement transducer used in the system is an absolute device with no periodic calibration requirements. It is free of short term drift and long term changes, as its accuracy is based on a very stable internal glass grating whose movement is optically monitored by a laser. The dual pushrod universal model (2 or 4 samples) may be operated either as a two sample absolute or a conventional differential dilatometer. Up to two furnaces can be configured on the same platform. Additional furnaces can be easily exchanged by the user. The plate specimen furnace (Model 1021 through 1024) is designed to test polymers and other low thermally conductive materials by placing the flat sample in direct contact with the heating/cooling surface to minimize thermal lag during controlled-rate heating/cooling.
