ETW-A Expert Torque Audit Wrench

The ETW-A Electronic Torque Audit Wrench is designed to give an accurate measurement of the residual torque on a previously tightened threaded fastener. The results are more reliable then standard torque wrenches as the torque measurement is taken when the bolt is rotated through a pre-set small angle, usually 2 to 4 degrees. The proprietary algorithm then calculates the residual torque and displays it on the units screen. Variations due to operator influence are eliminated in this mode. The Audit Wrench can also be used to tighten fasteners to a pre-set high-low range. The Audit Wrench comes with multiple languages and data stored on the unit can be downloaded to a PC.
