GBD-S Tear Tester - GBD-S

Function and usage
Mainly test the tear property of paper , mainly using for tearing strength of not more than 1000mN quantitative paper, plastic and foil.
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.
Unit construction principle
Tearing tester elmendorf method is made up with pendulum bracket, pendulum, shaft, stationary clamp, movable clamp, augmenting weights, knife, pendulum releasing system, and computer.
