DTM-II Dynamic Elastic Modulus Damping Internal Friction Analyzer (Resonance Method)

This instrument uses dynamic method (resonance method) to measure the dynamic elastic modulus and damping internal friction of metal materials, engineering ceramics, functional ceramics, non-metallic materials, graphite materials, glass materials, polymer composite materials, and concrete Measurement of elastic modulus at room temperature and high temperature ranging from room temperature to 1000 ℃. The instrument is widely used in factories, research institutes, and product quality inspection and testing departments for testing the elastic modulus of materials, and is adapted to standards such as GB 10700-92.
