Key Features

  • Features
  • Principle
  • Standard

1, Full touch screen control, automated and electronic measurement, easy to operate quickly

2, Pneumatic clamping of the sample, automatic cutting of the sample, automatic release of the pendulum, and automatic reset of the pendulum after testing greatly improve efficiency and effectively avoid system errors caused by human factors

3, The computer level adjustment auxiliary system can ensure that the instrument is always in the best testing state

4, Can be equipped with multiple sets of swing body capacities to meet different testing needs

5, Professional software supports data output from multiple testing units

6, Standard RS232 interface, convenient for external system access and data transmission.


Lift the pendulum up to a certain height to give it an initial potential energy. The pendulum tears the specimen while swinging down. Computer calculates the decreased energy caused by tearing to obtain the required force for tearing.
