Applications:

　　Important Characteristics Leading mechanical testing products manufacturer Zwick Roell Group’s HIT Pendulum Impact Testers are benchmark instruments for plastics manufacturers and processors.

　 　Accuracy, dependability and ergonomic design are primary features of the HIT pendulum impact testers. Advanced manufacturing technology brings improved accuracy specifications, with the following innovations and benefits for users in both R+D and quality.

Product Information:

　　l Pendulum coding as standard

　　The HIT Pendulum Impact Testers automatically recognize the pendulum being used and evaluate the test values in the correct range corresponding to the relevant standard. This ensures that different pendulum sizes or test procedures are used correctly, eliminating troublesome, error-prone fitting of additional pendulum masses as used by some pendulum impact testers.

　　l Virtually vibration-free

　　A world innovation is the use of double carbon rods for the pendulums, providing a high level of stiffness in the direction of impact and a strong concentration of the mass at the impact point. Compared to conventional single-rod, metal construction pendulums or compound type pendulums, the energy loss due to resonant oscillations is considerably reduced. The high stiffness level gives the pendulums excellent dynamic characteristics and prevents excessive forces in the pendulum rod during operation, for example if lzod specimens are only partially broken.

　　l Tool-free pendulum change

　　Each pendulum is equipped with a quick change unit, allowing changing of pendulums to be carried out quickly without special tools. Significantly there are no mounting components which can be easily lost with a resulting change in pendulum energy.

　　l Low-wear disc brake

　　The optional pendulum disc brake is virtually wearfree.

　　l Ergonomic design

　　Important operating elements such as keyboard, brake, release lever and display are all at one level within easy reach of the operator.

　　l State-of-the-art electronics

　　The new control electronics contain a high resolution digital encoder for precise measurement of the impact angle. For integration into laboratory management systems an RS232 interface is included. PC connection is via a USB upstream interface.

　　l Pendulum instrumentation

　　Instrumented pendulums and add-on electronics are available and provide a high-precision record of the rapid sequence of specimen impact and fracture. Each of these pendulums uses Zwick’s plug and play sensor connection system.

　　l High performance PC-Software testXpert II (optional) offers evaluations to DIN, ISO and ASTM. Reports and data archiving are performed in normal Windowsformats.
