Product Description: 
   This machine is testing the rebound elasticity of the vulcanized rubber. The test method is to move the needle bar so that the pointer is at the position of 100 on the scale, and then let the needle bar fall freely. When reading the fourth sound, the rebound height is The rebound elastic modulus of the sample.
