Elmendorf Tear Tester

Device Description

The Xell Elmendorf Tear Tester was especially developed for the paper industry. I features an easily exchangeable pendulum with automatic pendulum recognition. As a standard the 16 000 mN pendulum will be delivered.

Completely automatic test cycle. 10″ touch screen with latest PC technology is integrated. Sturdy base construction of the tester.

After the test the pendulum returns automatically to starting position and opens the clamps for exchanging the samples.

Test Description

The sample to be tested is placed between the clamps. With automatic detection of the sample the tester clamps the sample and the test cycle starts automatically. Clamping of the sample, cutting, release of the pendulum, pendulum swings and the value is detected, pendulum is pushed back in starting position – without breaking the pendulum to zero. Clamps will open and give the destroyed sample free for the next test. The automatic detection of the sample can be switched off, then you have to use a start-button on the screen.

Switch over from MD to CD is done by pushing the MD / CD button on the screen. Then the values are stored in 2 different statistic rows and afterwards the ratio between the MD and the CD samples will be calculated.

On the screen the last value will be displayed in big figures. The statistic values and a graph with the single values for comparison of the MD and CD values will be displayed as well. The 100 last measured values are also stored in the instrument to prevent data loss in case the values have not been not printed out or stored to a PC.
