TT-IMP Impact Wrench Torque Tester

Made in the USA The Checkline Europe TT-IMP Impact Torque Wrench Test System has been especially designed with a heavy-duty construction for the demanding purpose of testing impact tools. The torque measuring transducer is fixed in a sturdy frame which has been 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 custom 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 KG-m, N-m, lb-in or lb-ft (selectable) units with an accuracy of +/- 1% (bi-directional with optional reverse threaded run-down-fixture).

The TT-IMP Series of torque testers have been designed for demanding precision testing of pneumatic impact tools and geared wrenches. The TT-IMP Series is characterized by the heavy duty construction which makes it applicable in nearly all industrial areas . Due to the integrated reaction arm, capacities up to 3400 Nm can be tested.

Commonly used for testing Ingersoll Rand, DeWalt, Milwaukee, Westward and many others.


  • Heavy Duty Construction
  • Solid machined aluminium plate for weight reduction and long term durability
  • Spline engagement of run-down into torque transducers improves durability of transducer
  • Test stand is designed with feet to accomodate bolting test stand to bench
  • Capacity of up to 3400 Nm
  • Complete test system ready for use
