Description
Product Introduction:
This instrument is used to determine the thermal expansion and contraction properties of metallic materials, ceramics, glass, glazes, refractory materials, and other non-metallic materials during heating and firing.
Reference standard:
GB/T 3810.8-2016 and ISO 10545.8-2014: Determination of Linear Thermal Expansion of Ceramic Tiles,
GB/T 16920-2015: Determination of the Average Linear Coefficient of Thermal Expansion of Glass,
GB/T 3074.4-2016: Determination of the Coefficient of Thermal Expansion of Graphite Electrodes,
GB/T 7320-2018 “Test Method for Thermal Expansion of Refractory Products,”
GB/T 4339-2008 “Determination of Thermal Expansion Characteristic Parameters of Metallic Materials,” among others.
Product Features:
The thermal expansion coefficient tester, connected to a computer, provides automated temperature control, data recording, storage, and printing, generating a temperature–expansion coefficient curve. All test procedures are performed via the computer interface, ensuring ease of use and quick learning, with a complete software package included.
