Features
High Resolution
Using a shaftless encoder allows angle resolution of 0.045 °
Energy Losses
Shaftless encoder for angle measurement rotates without friction, thereby offering the lowest energy loss.
Touch Screen Display
Touch screen provides easy setup of specimen dimensions, pendulum energy, units and calibration data. The unit can also intuitively display test results such as absorbed energy and impact toughness
Interchangeable Pendulum
Simply change the pendulum to satisfy Charpy, Izod and tensile impact tests
Center Alignment
Rotating design allows for a quick and accurate specimen center alignment for the Charpy test
Supports and Anvils
Supports are firmly tightened and only require the remove of two bolts to change the supports
Broader Test Space
Single column structure offers broad test space. The machine allows for easy installation of low temperature impact test accessories in the future
