TST‑C1003B Yewellkang Compression Set Tester
The Yewellcon compression set tester is used to ...
Sponge Foam Rebound Coefficient Tester is suitable for determining the drop ball rebound resilience of flexible cellular polymeric materials.
It can automatically record rebound rate and calculate average rebound rate. Equipped with a ring shaped anti interference device, this technology shields external interferences against infrared signal acquisition, achieving a data capture rate up to 96%.
A steel ball with specified mass and diameter falls from a fixed height onto the specimen surface. Measure the rebound height of the steel ball, and calculate the percentage ratio of rebound height to drop height.
ASTM D3574 and ISO 8307:2007 (Flexible cellular polymeric materials — Determination of rebound resilience by ball drop method)
GB/T 6670-2008 (Flexible cellular polymeric materials — Determination of rebound resilience by ball drop method).

1. 【Attractive Appearance】
The main frame is constructed of silver grey painted steel plate and APS high strength aluminum alloy profile supports, fastened with stainless steel screws (non-electroplated) for an elegant appearance.
2. 【High efficiency Data Capture】
Equipped with a ring shaped anti-interference device. This technology shields external disturbances to infrared signal acquisition, achieving a data capture rate as high as 96%.
3. 【Dual standard Switching】
Supports both 460mm rebound coefficient for Chinese national standard and 500mm rebound coefficient for ASTM standard. Freely switch between the two standards by manually sliding the adjustment unit.
4. 【Automatic Error Correction】
The microcomputer automatically compensates for measurement deviations to guarantee accurate test results in case of errors.
5. 【Easy Operation】
Adopts TST intelligent control system with Chinese language menu. It features simple operation, abnormality alarm, low routine maintenance and one click printout of test data.
6. 【Level Adjustment】
Built in spirit level enables direct visual inspection of horizontal status. The adjustable foot pads allow height adjustment for instrument leveling.
