Made in USA
Impact Torque Tester
Click images to enlarge.
The TT-IMP impact torque wrench test system is specially design with extra-rugged construction for the demanding job of testing impact tools. The torque measuring transducer is fixed in heavy-duty frame designed for secure bench top mounting. A digital display is connected remotely to isolate the electronics from the potentially damaging vibrations caused by impact tools. A specially designed run-down-fixture is supplied to simulate real-world application conditions, allowing the impact tool motor to ramp-up to freely rotate several times before building resistance to rotation.

The included digital indicator can display torque in lb-ft, N-m, Lb-in or Kg-m (selectable) with an accuracy of +/-1% (bi-directional with optional reverse threaded run-down-fixture).


  • Counts Pulses / Blows while displaying peak torque
  • Heavy Duty Construction
  • Solid machined aluminum plate for weight reduction and long term durability
  • Spline engagement of rundown into torque transducer improves durability of transducer
  • Test stand is designed with feet to accomodate bolting test stand to bench
  • Complete test system ready for use
