1 purpose
The equipment is used for mensurating the thermal expansion of refractory products.

2 execution standard
The equipment accords with the standard of GB/T 7320.1-2000 "Refractory materials_Determination of thermal expansion_Push rod method". The structure of the tester is reasonable. It's automatically controlled by industrial PC, includes comfy interface, high precision, good maintainability, operation very handily, prints testing result by itself. Atmosphere of the hearth is air, inert gas or vacuum. Prepare Germanic standard sample. It can bring out the curves of distortion-time, temperature-time, distortion-temperature, expansion rate, and can be searched by the third party in EXCEL database for saving test result.
Security: Prepared over-current, over-voltage warning devices.
