HY8120 Linear Thermal Expansion Tester is used to determine the coefficient of linear thermal expansion of solid inorganic materials and metal materials, such as corundum, refractories, ceramic products, ceramic raw materials, glass, graphite, etc. The sample in this machine can be protected by atmosphere as required by the user, also the machine can be vacuumed and the vacuum degree is 0.1MPa.
GB/T 3810.8, 16920, 3074
★ Adopt imported linear bearing transmission to realize non-friction transmission of expansion value, excellent transmission accuracy and repeatability.
★ With standard computer interface, can connect to computer for whole operation, more convenient. The computer automatically calculate expansion coefficient, volume expansion coefficient, linear expansion value, shock thermal expansion (Computer is optional).
★ Automatically record, store and print test data, print temp.-expansion coefficient curve (Printer is optional).
★ The temperature interval is settable, the minimum interval can be 1℃.
