LT-JJ37 Sponge Elastic Resilience Coefficient Tester

Short Description:

This Sponge Elastic Resilience Coefficient Tester determines the resilience (rebound coefficient) of flexible cellular polymeric materials, such as polyurethane foam, by measuring the rebound height of a steel ball dropped freely onto a specimen. Compliant with the Chinese National Standard GB 6670-86 (aligned with ISO 8307), the instrument utilizes photoelectric sensing and electromagnetic control for precise, repeatable measurements displayed digitally. It uniquely combines instrumental and visual observation methods to enhance reliability, minimize human error, and provide an accurate, user-friendly solution for assessing the impact resilience of soft foams and other elastic materials.
