Function

Class J Impact Testing System is widely used for lzod and Charpy impact test on plastics and rubber specimens. Equipped with tensile impact pendulum and fixtures, it can carry on tests on plastic film and sheet. The newly enhanced design offers the most cost-effective configuration to address Charpy test from 1J to 50J, and lzod test from 1J to 22J.

Automatic Pendulum Impact Testing Machine

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 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

Automatic Pendulum Impact Testing Machine

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
