  • Product description

    The  Elmendorf  tear  tester  has  been  developed  specially  for  the paper industry ans is outstanding for simplicity of operation and  high  measurement  accuracy.   The exchangeable pendulum is equipped with a pneumatic sample clamp. The initiation and return of the pendulum, as well as sample cutting is completely automatic. The device is operated via an integrated touch screen, where the test method can be selected, specific settings can be adjusted,  and,  after  the  measurement,  results  and  statistics   can be displayed. Each pendulum is supplied  with the appropriate control weight so that, with the help of the service program,  it can easily be checked for functionality and balance.


    Test description:
    Up to 16 samples  (acc. to standard 4 samples), prepared with the sample punch (ref : N3001), are laid one on top of another and placed in the sample holder. On the touch screen, the number of samples inserted is selected, these are allocated to a test series (MD/CD) and the start button is pressed. The samples are automatically clamped and cut with a blade. Then the pendulum is automatically initiated and tears the sample above the cut. The pendulum is slowed, returned automatically to the start positionand teh destroyed samples are released.  The force required to tear the sample is displayed on the touch.
