Digital Torque Calibrator is a device used to ensure that torque tools, such as torque wrenches, are measuring accurately. The calibrator applies a known amount of torque to the tool being tested, and the resulting reading is compared to the expected value to determine if the tool is measuring correctly. Moreover, the accuracy of a digital torque calibrator is determined by several factors, including the quality of its electronic components, its calibration procedure, and the skill and experience of the technician using it.
