The instrument used to detect the solid inorganic material, high temperature expansion properties of the metal material, in particular corundum, refractories, casting with a shell and core materials, ceramics, ceramic materials, porcelain clay, glaze, glass, graphite, carbon printed materials and other inorganic materials, the performance of metal products, for research and teaching to provide the necessary means test. The instrument can be completed through the sample line variable, linear expansion coefficient, body expansion coefficient, softening temperature, kinetics of sintering, the glass transition temperature, phase transition, density, sintering rate control (RCS) and their curves. According to customer requirements for sample atmosphere protection, vacuum, vacuum of 2.66 × 10-2Pa. ● also applies to GB / T3810.9, GB / T3810.10-1999 ceramic tiles Determination of linear thermal expansion. ● LCD display real-time status of the instrument and data. ● test the heating rate is set by the users themselves, the software PID control linear warming. ● You can calibrate the instrument using standard samples of the indicators. ● measurement process automatically, automatic drawing, can also be manually corrected, the computer automatically calculates the coefficient of linear expansion coefficient of expansion body, linear expansion, the rapid expansion. ● import displacement sensor, high accuracy and good reproducibility. ● LCD display real-time status of the instrument and data. ● test the heating rate is set by the users themselves, the software PID control linear warming. ● You can calibrate the instrument using standard samples of the indicators. ● measurement process automatically, automatic drawing, can also be manually corrected, the computer automatically calculates the coefficient of linear expansion coefficient of expansion body, linear expansion, the rapid expansion. ● import displacement sensor, high accuracy and good reproducibility.
