SATRA STD 645 Digital resilience tester

The STD 645 is a sturdy bench-mounted instrument designed to meet the requirements of the rubber industry.

Rebound resilience (elasticity) facilitates a simple method of measuring damping properties and is commonly used in conjunction with hardness testing for basic quality control.

The sample is located against a polished anvil and secured by spring clips. Adjustment can be made to accommodate differences in sample thickness. The pendulum is released from a horizontal position and strikes the sample at a vertical point. Its rebound height is displayed digitally as a percentage of its distance from the horizontal start position.
