Elmendorf Tearing Strength Tester

Mainly test the tear property of paper, Mainly using for tearing strength of not more than 1000mN quantitative paper and paper board.

Test Principle:

Lift the pendulum up to certain height, enable it to have a certain potential energy, Pendulum tears the specimen while swinging down, computer calculates the decreasing energy caused by tearing
