It is made to measure soft foam polymeric material falling ball rebound rate. A certain mass and diameter of the ball, falling from the fixed height down to the sample surface, then measure the height of the ball bounce, calculate ball bounce height and the percentage of the drop height ratio. This machine comes with microprocessor control, LCD display and it is able to print the test data. It is safe to use, reliable and higher measurement precision.
