Checkline AWS TT-IMP Impact Wrench Torque Tester

The TT-IMP impact torque wrench test system is specially designed with extra-rugged construction for the demanding job of testing impact tools. The flange-mounted transducer is fixed in a heavy-duty frame designed for secure bench top mounting. A digital display is connected remotely to isolate the electronics from the damaging vibrations caused by impact tools. A specially designed spline drive run-down-fixture simulates 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).

The TT-41000 Series impact torque testers are designed to check tool operation and consistency. The measured torque value does not precisely indicate the effective clamp load of the bolt. It is common for tool manufacturer's specified torque output to vary by +/-20% versus what the TT-41000 will indicate however the critical value is repeatability, not measured output.

The TT-IMP is designed for use with impact and impulse tools only. It is not compatible with hand torque wrenches or reaction tools. The display included with the TT-IMP can be used with our IT Transducers to extend its capabilities.
