83-76 Elmendorf Tear Tester


83-76 Elmendorf Tear Tester


An automatic, digital tear tester equipped with an optical encoder for measuring the angular position of the pendulum during tearing and converting this measurement to tear strength units. A large, full-color touchscreen display with intuitive, easy-to-use software provides a revolutionary new approach to testing and data review.

Elmendorf Tear testing determines the force required to continue the tearing of an initial cut in sheet materials such as paper, plastic film, textile and non-wovens.

Easy-to-use touchscreen interface

The model 83-76 features a dynamic digital touchscreen user interface that allows for complete user interactivity and instrument control.  The 7” full color screen displays a resolution of 800×480 pixels and provides optimal viewability at almost any angle.

Software features include custom test and sample IDs, data export via RS-232 and USB, maintenance/diagnostics menus and more.

Calibration of the pendulum is accessed through the touchscreen interface and is completed automatically in a few simple steps.

Pneumatic clamps

Simple, two-button operation of the pneumatic clamp and swing operations ensures efficient and repeatable measurements of tear strength.  A built-in cutting blade prepares samples for testing.

Universal pendulum

A universal pendulum with tool-less hardware and interchangeable weights provides multiple testing options.  The required calibration weights are included in the set.
