Chuck-Style Torque Tool Testers


Finger-tighten the three-jaw chuck onto a torque wrench or screwdriver, then twist either the gauge or tool to check the tool's accuracy. Use with hand tools only. A pointer shows torque as it's measured. Testers with memory pointer show the maximum torque reached.
Note: The accuracy ratings do not apply to the lower 10% of the torque range.

Chuck-Style Digital Torque Tool Testers




Measure the torque output of torque wrenches, screwdrivers, and other hand tools to ensure they deliver the right amount of torque—and check your results on a digital screen. Cycle through four units of measure on the screen, then set it to display real-time or maximum torque. These testers have a keyless chuck that's similar to a standard drill chuck: insert the tool you're measuring and tighten the chuck by hand. They can also be used to measure the torque consistency of small rotating parts, such as motors, potentiometers, and encoders.
Testers with calibration certificate with test data traceable to NIST include the test measurements that confirm accuracy.
The tester's memory keeps track of up to 999 different measurements. Use the USB cable and software download link (sold separately) to transmit, store, and analyze test data on a computer. The software stores time, date, and torque measurement values that you can import into Microsoft Excel.
To use the tester on external power, add an AC adapter (sold separately) and attach it with the USB cable (sold separately with the software). Adapter cannot be sold in Canada due to energy efficiency requirements.
For large and oddly shaped items, use a testing fixture (sold separately). Testing fixtures fit inside the tester's chuck and have four clamping pins that allow you to hold objects as wide as 2 1/4".
For handheld use, the display fits inside the back of the tester. To use the tester on a flat surface, remove the display from the back of the tester. For additional stability, mount the tester onto a testing stand (sold separately). Testing stands have four pins that fit inside the tester to anchor it, a handle for leverage, and mounting holes for permanently securing the stand.
