Zwick introduced new HIT series of pendulum impact testers in 2005 and 2006 with impact energy ranges of 5.5 Joule, 25 Joule, and 50 Joule, and has already been very successful in the global market. A new compact 5 Joule ISO machine with an extremely compact construction has been developed for Charpy and impact tensile testing. This is achieved by using short ISO pendulum hammers and restricting the measurement range.

The tester possesses the same advantages as the larger machines, and uses the low-vibration, double-rod carbon pendulum, which features very high rigidity in the impact direction and a high concentration of the mass at the point of impact. The automatic pendulum recognition (APR) system means that the test results are traceable even if different pendulums are used. Additional advantages are the slip-proof tool fixtures with dovetail guides and a convenient USB interface for connecting to the testXpert II software.

The larger pendulum impact testers were also improved and Zwick has added a new motorized pendulum lifting unit together with a new CE-conforming protective shielding. This increases the operating convenience significantly especially for the large 25 or 50 Joule pendulum hammers. In addition, the motorization is an important precondition for the automation of the impact tests.
