Calibration System vs Tester

Torque calibration systems are more accurate than testers, due to their sophisticated electronics combined with finely geared mechanical loaders, which apply consistently precise torque to the tool being calibrated (adjusted) and certified.

Torque testers are used too quickly to check the accuracy of a torque wrench, and should not be used for calibration.

“Testing” is normally performed between calibrations as periodic confirmation that the torque wrench is operating properly.

Torque testers are also effective to train torque wrench users on how to properly apply torque.
