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).

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.

Keep torque-limiting power tools, such as air-powered tools and impact drivers, calibrated and prevent fasteners from loosening or failing because of under or over tightening. Use these testers to record the first time your maximum torque is reached (peak down), the maximum torque (peak), or torque as it's measured (real-time). Connect your power tools to the testers using the flexible or rigid joints to simulate your fastening application. If necessary, use the included drive adapter with one of the joints. All of these testers include a calibration certificate with test data traceable to NIST that states they have passed three separate tests to confirm accuracy.

Testers that meet ISO-17025 standards give you added confidence that the testing laboratory generates valid results.

To analyze results or document readings, use the data acquisition software and USB cable (each sold separately) to send results to computers, laptops, or tablets that run on Microsoft Windows.

Measure the twisting force needed to tighten tops, loosen lids, and turn potentiometer knobs or valve wheels. These testers are often used to fine-tune automated capping machines, or to help design bottling and packaging processes. An adjustable clamp holds your container in place while you open and close the cap. Four posts on the clamp can be moved to fit objects of any shape.

Store your data on the included Micro SD card, or send it to tablets and computers using Bluetooth or a USB connection. Connect to a controller using the I/O cable to control other devices dependent on torque readings. The RS232 cable lets you send data directly to your printer to create reports or labels.

Choose a torque range that is greater than the force you will be testing. These testers have overload protection, which prevents damage to the measuring system if you accidentally exceed the torque range.

Testers with a calibration certificate with test data traceable to NIST adhere to strict guidelines for accuracy.

Calibrate torque screwdrivers, both hand and non-impact electric styles, on your production line and put an end to fasteners loosening or failing from under or over tightening. These testers have chuck-like joints that simulate your fastener joints. Place a joint in the tester, insert a fastener, and then drive the fastener with your screwdriver to measure the torque. Press the Clear button when the test is complete and the fastener automatically returns to its starting positon to reduce the time between tests. Use these testers to record the first time your maximum torque is reached (peak down), the maximum torque (peak), or torque as it's measured (real-time). A track mode lets you monitor fluctuating torque. For quick pass/fail testing, these units have programmable high/low set points with lights and an audible alarm that alert you to the results. They include a calibration certificate with test data traceable to NIST that states they have passed three separate tests to confirm accuracy. Do not use them with air tools.

To analyze results or document readings, use the data acquisition software and USB cable (each sold separately) to send results to computers, laptops, or tablets that run on Microsoft Windows.

Use these gauges with changeable sensors and square-drive sockets (sold separately) to display, collect, and download torque readings. They display torque as it's measured and the maximum torque reached. Gauges can also be used to convert any hand-turned square drive tool into a precise torque-measuring tool.

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

Wrench-attachable sensors fit between your wrench and socket. Use with hand tools only.

Hand-turned sensors don't require a tool; place into your socket and turn them with your hand.

A dial shows how torque measurements change as you turn the driver. Use these tools to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Calibration certificate traceable to NIST states the product has passed a test for accuracy.
