TMI 83-76 Elmendorf Tear Tester

Product Ref: TMI 83-76

An automated tear tester equipped with an optical encoder for measuring the angular position of the pendulum during tearing and converting this measurement to tear units.

Introduction

An automated tear tester equipped with an optical encoder for measuring the angular position of the pendulum during tearing and converting this measurement to tear units. A large, full-color touchscreen display with intuitive, easy-to-use software provides a revolutionary new approach to testing and data review. Tear testing determines the force required to continue the tearing of an initial cut in sheet materials.  This method is also used to evaluate strength of perforated materials such as postal reply cards.
