For ease of use, this simple to use tester is equipped with a touch screen. The progress of the test is displayed on the screen. Charts, single and statistical values are displayed immediately at the end of the test. The robust housing is set up on specially developed vibration dampers. The acryl cover keeps air blasts and other external impacts away that might lead to incorrect results particularly when low forces are applied. Bending angle, angular velocity, dwell time and other parameters can be preselected. Norm-based testing methods are predefined. User-defined test methods can be stored.

Test description:

A specimen is set up and, in the manual version of the tester, clamped by means of a torque screwdriver. With the pneumatic version of the tester, the specimen is clamped automatically when the start button is pressed. The specimen loader releases the specimen for the measurement and the specimen is pressed into contact with the bending cutters of the force transducer. The curve is already displayed while the measurement is still in progress. When the present bending angle is obtained, the specimen stops and is held for the preset dwell time, after which it returns to the starting position.

The automatic version releases the specimen automatically. The test results and the test curve are displayed. When longitudinal and transversal tests are carried out, a ratio of both is also displayed.
