Torque tester
From Wikipedia, the free encyclopedia
A torque tester is a quality control device to test or calibrate torque-controlled tools. This includes electronic torque wrenches, click torque wrenches, dial torque wrenches, electric screwdrivers, air screwdrivers, pulse tools, cordless screwdrivers, nutrunners, and torque screwdrivers. Advanced torque testers include the ability to measure in clockwise and counter-clockwise directions,[1][failed verification] and potentially convert to engineering units (such as in·oz, in·lb, ft·lb, N·m, cN·m, kgf·cm, gf·cm, kgf·fm). They can also have different modes of operation (such as peak, 1st peak, track), and may include a certificate from a local regulator (such as NIST).
Torque testers measure properties such as torsional strength and stiffness and are used in quality control of various fields including medical devices, metals, and aerospace.[2] Cap torque testers are also frequently used of measure the removal torque of screw caps on bottles and jars.[3]
