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.

These testers have a digital display and are accurate to ±1%. Place your torque wrench or screwdriver onto the tester with the included square drive connector and turn. Testers display torque as it's measured and the maximum torque reached. They also show the first torque peak reached to ensure accurate readings when testing click-style wrenches. Use with hand tools only.

Note: The accuracy ratings do not apply to the lower 10% of the torque range.

Calibrate torque-limiting power tools such as air-powered and impact drivers. These testers check clockwise and counterclockwise torque, so fasteners do not fail because they were too loose or over-tightened and deformed. They record the first time your maximum torque is reached (peak down), the maximum torque (peak), and torque as it's measured (real-time). Use the flexible or rigid joints to connect your tools to these testers to simulate your fastening application. These testers have a calibration certificate with test data traceable to NIST, so they meet standards for accuracy.

Testers that meet ISO 17025 have been checked in a laboratory that was evaluated for accuracy.

Connect to computers, laptops, or tablets that run on Microsoft Windows with a USB cable and analyze results with data acquisition software (both sold separately).

Testers cannot be sold to California or Oregon due to energy efficiency requirements.

Measure the twisting force needed to tighten or loosen caps and knobs with these torque testers. Four adjustable gripping posts clamp round and irregularly-shaped containers. Twist the top by hand to measure force or use it to calibrate your capping machine, so it applies the right amount of force in a production line. These testers have overload protection, which prevents damage to the measuring system if you accidentally exceed the torque range.

View torque measurements, change operating modes, and switch units of measurement on the LCD screen. Store data on the microSD card, transfer it to your devices via Bluetooth or USB, or print using the DB9 cable. The I/O cable connects to controllers to operate other devices dependent on torque force readings.

Testers with a calibration certificate with test data traceable to NIST meet standards for accuracy.

Measure the force of hand and non-impact electric torque screwdrivers to keep fasteners from failing due to under or overtightening. A chuck-like adapter simulates your fastener joint during testing. Return the fastener to its starting position with the press of a button to reduce time between tests. These testers record the first time you reach the maximum torque (peak down), the maximum torque (peak), and torque as it's measured (real-time). A track mode lets you monitor fluctuating torque. For quick pass/fail testing, these testers have programmable high/low set points with lights and an alarm. They include a calibration certificate with test data traceable to NIST that states they have passed tests for accuracy.
