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.
Bench-top testers can be mounted to your work surface. Those with a gooseneck display can be bent until you can clearly see the test results. Mount these testers to your workbench with a mounting bracket (sold separately). Or, carry them where they’re needed using the included case.
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.

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).
