The falling ball rebound instrument is designed and manufactured according to GB/T6670-2008 or ISO8307 or ASMD3574. It is suitable for determining the falling ball rebound property of soft polyurethane foam. The instrument calculates the maximum rebound height of the steel ball and the percentage of the falling height of the steel ball by the steel ball with a given diameter and quality falling freely on the foam sample at a specified height, and the rebound rate represents the resilience of the foam.

Standards

Complies with international testing standards such as ASTM D2632. ISO 6272. and relevant national standards.

Meets calibration and measurement accuracy requirements for material impact testing.

Follows safety and quality guidelines for laboratory instruments.

Features

Computer-controlled operation for precise and repeatable testing.

High-resolution sensors for accurate rebound measurement.

Adjustable ball drop height to test different material types.

Digital data acquisition and storage with analysis software.

Compact, durable design with easy-to-use interface and safety protections.
