  • Mechanical calibration system up to 400 Nm for torque wrenches and torque screwdrivers.

  • A special force transmission system prevents the point at which the force is applied from shifting during the calibration process.

  • A handwheel drives a lever, which is moved linearly via a spindle, thereby transmitting a rotary motion to the sensor.

  • Reduced shear force on the transducer and low-friction support for the torque wrench mean measuring errors are largely avoided.
