1.Description:
This instrument is suitable for measuring the volume changes (expansion and contraction) of metal materials, ceramics, glazes, refractory materials, plastics and other non-metallic materials that occur with temperature changes ranging from -30ºC to 100ºC.Automatic temperature control, data recording, storage, and printing. It can print temperature-expansion coefficient curves. All test operations are completed through the computer interface. The operation is convenient and easy to learn, and it comes with a complete set of software.
2.Standard

GB/T 3810.8-2016 specifies the method for determining the linear thermal expansion of ceramic tiles; GB/T 16920-2015 specifies the method for determining the average linear thermal expansion coefficient of glass; GB/T 3074.4-2016 specifies the method for determining the thermal expansion coefficient (CTE) of graphite electrodes; GB/T 7320-2018 "Test Method for Thermal Expansion of Refractory Products"; GB/T 4339-2008 "Determination of Thermal Expansion Characteristics Parameters of Metallic Materials", etc.
