  • The weighing head, with a precise strain gage torque sensor, is cleverly mounted on a movable unit for easy rail positioning
  • Accommodates specimens of different lengths, enhancing testing versatility and precision
  • An adjustable crosshead locking system provides flexibility, allowing the crosshead to be either free-floating or fixed during testing
  • Equipped with extra-wide frames and personalized grips
  • Real-time display of test data (torque, twist angle, etc.) with curve recall and reporting
  • User-configurable testing methods and report templates for different materials
  • Multiple control modes present like stroke, torque, twist angle, stress, shear strain, etc
  • Comprehensive test parameters include torsional strength, yield strength, and more
  • Safety indicators to alert errors during testing
  • Automation features like zero adjustment, calibration, and data storage are available


It is used to determine the torsional properties of various components – from fasteners to biomedical devices and it determines the torque load and behavior of the specimen. It evaluates the mechanical properties of materials, particularly metals, and alloys, under torsional forces.
