Tear tester   Elmendorf tear strength test

Test the force required to tear a certain number of precut sheets, such as paper, plastic film, fabric and non-woven fabric.

It is equipped with an optical encoder to measure the angular position in the pendulum tear and convert this test amount into tear units.

At present, Elmendorf method is mostly used to test the tear strength of packaging materials, including paper, film, fabric, etc. Elmendorf method is a pendulum tearing method. It tears the sample by measuring all the potential energy of the pendulum at a certain initial height after it is converted into kinetic energy, and then converts it into the work used to tear the sample through the reduction of its potential energy, and calculates the average tearing force according to the original length of the sample. Because of its simple structure, easy to use, stable test data and many other advantages, it is still widely used in many industries such as textile, paper, packaging and so on. The difference is that the sample preparation standards of various industries are different.

Equipped with: optical encoder, which is used to measure the angle position in the pendulum tear and convert this test amount into tear unit. The intuitive full-color touch screen display and easy-to-use software make the test,

data acquisition and data query more convenient.
