Specifications subject to change without notice!

A test sample of defined size and thickness is clamped onto the test plate. The test plate is tilted by 30° into the test position, thereby bending the sample under test. The sample presses against the force sensor and the measured force is displayed in newtons (mN).

Delivery Includes

Stiffness tester KWS with transport packing case, AC-adapter, torque wrench and operating instructions in German or English.
