Trust the Thwing-Albert Electronic ProTear to measure Elmendorf Tear Strength of a variety of materials. Thwing-Albert is the original manufacturer of the Elmendorf Tear Tester which was designed by Dr. Thwing and Mr. Armin Elmendorf. This method developed over a century ago established the industry standards used worldwide today to measure tear strength.
The ProTear provides a rapid and precise way to evaluate the tear resistance of sheet materials including paper, textiles, roofing products, plastic film, and foils.
The electronic model features a touch-screen panel that allows for a simple one-touch process to run tear tests and track data. Two different pendulums are available with various augmenting weights and can be configured to meet capacities from 200g-12,800g. MAP4 Software can be used to evaluate the sample test results with dynamic tear data calculated at every point of the test to allow for real-time data as the sample tears.
