Chuck-Style Digital Torque Tool Testers
 Tester Shown with Stand and Fixture (Sold Separately) |  Tester |  Testing Fixture | |
 Testing Stand | |||
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.
Note: For the most accurate performance, the maximum torque you apply should fall near the middle of the tester’s torque range.
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.

Torque Testers for Torque-Limiting Power Tools
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. For the most accurate performance, the maximum torque you're applying should fall near the middle of the tester's torque range.
Torque Testers cannot be sold to the listed areas due to energy efficiency regulations.
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).

High-Accuracy Torque Tool Testers
Accurate to within ±1%, these torque testers are often used to check the accuracy of torque wrenches and screwdrivers on assembly lines. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. To test, place your torque wrench or screwdriver onto the tester with the included square drive connection and turn. These testers display torque as it's measured and the maximum torque reached. For accuracy when testing click-style wrenches, they also show the first torque peak reached. They’re not for use with impact or pulse tools.
Note: For the most accurate readings, the maximum torque you're applying should fall near the middle of the tester's torque range.
Portable testers are lightweight and easy to move around your facility. Their touch-screen display makes it easier to navigate through different menus than testers with a digital-screen display. To view data in a CSV file, pop out the tester’s SD card and plug it into your computer. You can also transfer data by connecting the tester directly to your computer with the USB cord. To use these testers with nonimpact power tools, they include at least one socket screw adapter. These testers meet ISO 17025, so they’ve been checked in a laboratory that was evaluated for accuracy.

Torque Tool Testers for Torque Screwdrivers
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. 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). For the most accurate performance, the maximum torque you're applying should fall near the middle of the tester's torque range. 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.
Testers that meet ISO 17025 have been checked in a laboratory that was evaluated for accuracy.
Testers with automatic screw release reduce time between tests by returning the test screw to its starting position once torque is removed.
Use data acquisition software and a USB cable (each sold separately) to analyze results and connect to computers, laptops, or tablets that run on Microsoft Windows.
Testers cannot be sold to the listed areas due to energy efficiency regulations.

Data-Recording Torque Gauges
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. For the most accurate performance, the maximum torque you're applying should fall near the middle of the gauge's 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.

Digital Torque-Measuring Screwdrivers
A green light and a beep alert you when you've reached 90% of your set torque, and a steady tone sounds once you've hit your target. Set your torque in cNm, cm-Kg, or in.-lbs. and quickly check the LCD for real-time measurements along the way. A red light warns if you begin to overtighten. In addition to applying the correct torque to a fastener, these screwdrivers can help determine fastener torque specifications and identify the torque required to loosen tightened fasteners. They store up to nine torque settings to save time when working on multiple fasteners. They're compatible with any bit that has a 1/4" hex shank. All require one AAA battery (included). To save battery power, the display turns off after five minutes of idle time. You can also turn the display off manually.
Accurate to within 2% of the set torque in the clockwise direction, and 3% in the counterclockwise direction, these screwdrivers are more precise than standard torque screwdrivers. All screwdrivers come with a calibration certificate from the manufacturer. Screwdrivers with calibration certificate with test data traceable to NIST include the test measurements that confirm accuracy.
