TN4208 Foam Drop Ball Rebound Resilience Testing Machine
1.It is suitable for soft foam polymeric material falling ball rebound rate measurement.
A certain mass and the 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 adopts the microprocessor control, LCD display, and can print the test data.
The machine has the characteristic for safety use, reliable, higher measurement precision.
2.Automatic computation average rebound debugging.
3.Automatic computation average rebound rate,Sponge resilient rate tester, product features.
4.Sample can be made by National standard 460 , and be made by American standard 500.(Similar products only can be
made by National standard 460)
5.LCD screen, English display, extend the life of tester, easy to understand.
Technical workers can master the operation method quickly. (the same products is displayed by digital tube which shows only
6.Equipped with printer to print the test report out.
1.Ball falling distance:460±0.5% mm(Chinese standard),500±0.5% mm(American standard)
2.Ball diameter:Φ16±0.05 mm
3.Falling ball rebound rate accuracy:1.5
4.The tested sample size:100 (L)*100 (W）*50 (H）mm
