Product info
The apparatus is used to measure temperature in the state of metal materials, ceramics, masks, fire-proof material and other non-metallic materials in the process of being heated roast expansion and contraction performance, also apply to the ceramic tiles linear thermal expansion tests.
Overview
TDM-VII high-temperature vacuum expansion meter is used to detect the high-temperature expansion performance of solid inorganic materials and metal materials, especially corundum, refractory materials, shell and core materials for precision casting, ceramics, ceramic raw materials, porcelain clay, glazes, and glass. , graphite, carbon and other inorganic (organic) materials, metal products, and the performance of polymer materials, providing essential testing methods for scientific research and teaching. The TDM thermal expansion meter is also suitable for measuring the linear thermal expansion of ceramic tiles, measuring the average linear thermal expansion coefficient of glass, measuring the coefficient of thermal expansion of graphite electrodes (CTE), and the "Test Method for Thermal Expansion of Refractory Products". It also fully meets the requirements of the State Food and Drug Administration. Packaging materials [Linear thermal expansion coefficient testing].
