Tear Tester

Tear tester,tearing strength testFunction and usageTear tester mainly test the tearing the paper , mainly using for tearing strength of not more than 1000mN quantitative paper and paper board.Test principleLift 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 principleTearing tester elmendorf method is made up with pendulum bracket, pendulum, shaft, stationary clamp, movable clamp, augmenting weights, knife, pendulum releasing system, and computer.Specifications Measuring range :0-1000MnTearing arm: 104 ± 1mmTearing the initial angle: 27.5 ± 0.5Indication error: In the power of the ruler maximum range of 20% -90% range, showing the value of the error should not exceed the maximum range of ± 0.5%Relatively change value: less than 1%Configuration Standard:Mainframe,200gf basic pendulum,1600gf augmentuing weight400gf,200gf check weight,communication cable,softwareOptional:Augmenting weight: 800gf ,3200gf,6400gfCheck weight: 400gf, 800gf, 1600gf,3200gf,6400gf,User-ownerComputer,gas source0.2-0.4MPa
