LT-JJ37 Falling ball rebound coefficient / sponge elastic rebound coefficient tester

 

The product description

The instrument is a steel ball falling freely on a soft foam or other elastic material sample. An instrument for determining the rebound height of polyurethane elastomer materials. Reference to national standards of the People's Republic of China, 6670-86 "determination of the soft foam resilience can; the instrument USES the photoelectric technology, electromagnetic control, digital tube display measurements, measurement accuracy, repeatability, etc., make a convenient, beautiful modelling by two kinds of visual inspection and instrument testing at the same time, both to increase the credibility of the instrument, and convenient for the user control use, for the accurate determination of soft elastic material such as plastic foam can rebound elasticity, reducing human error and visual fatigue instruments provides a feasible method.
