Leather Ball Burst Strength Tester UP-4001
Product Introduction
The ball burst tester, also known as leather cracking tester or Lastometer, is essential equipment for material physical property testing. It stretches the clamped specimen from underneath via a steadily expanding steel ball until grain cracking or bursting occurs, to measure the grain strength and resistance to last-forming stress of materials.
It precisely records burst height and burst strength in line with international test standards, delivering reliable test data for new product development, process optimization and incoming quality control.
Product Highlights
* Digital high-precision displacement & force sensing
* Stable steel ball expansion driving system
* Quick specimen clamping, easy operation
* Automatic data recording & report output
* Support multiple material specimens: leather, paper, nonwoven
