The AlphaFlex10™ is a high elongation tensile tester designed to measure a wide range of rubber materials, including elastomers and non-rigid plastics. It works by applying tensile force to a specimen that has been attached to a variety of counterbalanced clamps at pre-selected gauge lengths. An optical encoder measures the slightest change in gauge length when the specimen is put under force, sending signals into the conditioner interface for processing.
