The operation torque of the ST-TSB can be factory-set between 5-20 LbIn, upon the customers specification, and will repeat this torque with +/- 0,2 LbIn accuracy.
The ST-TSB can be used by any automatic or manual torque tester instead of a real bottle. Just place the Torque Standard Bottle on the torque tester, rotate the closure on either direction and compare the torque testers measured value with the Torque Standard Bottle’s torque range. Should torque tester measure values out of the Torque Standard Bottle’s torque range, the torque tester needs to be recalibrated.
