The device of the physical property tester (physical property analyzer, texture analyzer) can perform continuous testing, which is superior to the standard method of "leather cracking test" and can accurately identify the material yield point. The composition of the physical property tester (physical property analyzer, texture analyzer) includes a sample holder and a penetrometer.

The HDP/BAG bag clamp complies with the CEN standard method for measuring leather bags and can measure creep and stress relaxation properties. Measure whether permanent deformation of the sample is caused after a preset force or a specific time.
