This machine is an important instrument for testing the physical properties, structural properties and internal and external defects of various concrete materials and their products. It can realize the compression type test of metal or non-metal materials, can automatically obtain the compressive strength and other performance indicators of the measured material, and can complete the closed-loop control of constant rate loading, constant rate deformation, constant rate displacement, constant rate strain, etc. .
This machine is accurate, powerful, easy to operate, stable and reliable. It is widely used in universities, scientific research institutes, testing institutions, aerospace, military industry, metallurgy, machinery manufacturing, transportation construction, construction and building materials and other industries for precise material research, material analysis, material development and quality control. The process qualification performance verification test of materials or products can be carried out.
