UT2089A Elmendorf Tearing Tester is designed for the tearing test of films, sheets, flexible PVC, PVDC, waterproof films, woven materials, polypropylene, polyester, paper, cardboard, textiles and nonwovens.
Standard: ISO 6383-2-1983, ISO 1974, GB/T16578.2-2009, GB/T 455, ASTM D1922, ASTM D1424, ASTM D689, TAPPI T414
Principle: Lift the pendulum up to a certain height to give it an initial potential energy. The pendulum tears the specimen while swinging down. Computer calculates the decreased energy caused by tearing to obtain the required force for tearing.
Feature:
2.1. Automatic release of pendulum, high test efficiency
2.2. Sudden power-off data saving function, after power-on, the data before power-off can be retained and the test can be continued.
2.3. Cooperate with microcomputer software to communicate (separately purchased) ARM processor, integrated control board design, reduce the failure rate.
2.4. 7-inch color touch screen, Chinese and English operation, easy to understand and easy to operate.
