The DIW is a torque measuring manual wrench designed for verifying application or removal torque of bolts. The wrench head swivels 300° and can be used in tight places. You'll get consistent readings no matter where or how the wrench is gripped because the torque sensor is centered on the drive and not up in the handle. Torque controlled wrenches can also be evaluated by comparative tests on a given fastener. Both breakaway and loosen tests can be performed. Rugged enough to be used in production. Wrench head swivels 300°. This tester has an accuracy of ±0.5%, ±1 LSD. It offers a programmable setpoint for uniform tightening or Go/No Go testing and also provides peak data for SPC (statistical process control) via the USB port. Consistent readings no matter where the wrench is gripped because the torque sensor is centered on the drive.
