1PCY-D-II material high-low thermal expansion meterOverview of Linear Expansion Coefficient Tester:

Applied to detect the high and low temperature expansion properties of solid inorganic, organic materials, polymers, polymer materials, metal/non-metal materials, rubber, plastics, metal products, and other composite new materials. Applicable standards: ASTMD6962003, GB/T1036-2008 Determination of Linear Expansion Coefficient of Plastics - Quartz Dilatometer Method, GB/T2572-2005 Test Method for Average Linear Expansion Coefficient of Fiber Reinforced Plastics, GJB1875-94 Test Method for Thermophysical Properties of Rigid Cellular Plastics. The test method used is the plunger method, which uses (imported) high-precision micro sensors to sense the deformation values of samples at different temperatures. The detection, control, calculation, printing, and storage of samples are all automatically completed by computers using computer technology. This instrument can complete the sample line variable, linear expansion coefficient, volumetric expansion coefficient, softening temperature, glass transition temperature, and their variation curves. Adopting multi-stage refrigeration with a compressor (without liquid nitrogen), it is economical, convenient, and precisely controlled.
