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.

Rotary Torque Testers
Monitor torque as you apply it—these testers mount between your torque tool and your fastener. Engage the fastener to track both torque and the angle of rotation for each crank of your tool (snug torque) before you've reached the final torque. This gives you a better idea if fasteners are consistently tightened than measuring torque alone. These testers are often used with nutrunners and click-style torque wrenches in the automotive and aerospace industries. Store up to 999 maximum torque (peak) and rotation values, including the date and time of each test, or transfer to your computer to view in an Excel file. CE marked, they meet European safety standards.
For the most accurate readings, the maximum torque you're applying should fall near the middle of the tester's torque range. They are not for use with impact tools.
Testers with a USB connection transfer data directly to your computer with the included cord. These testers last up to 10 hours on a single charge.

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.

Opening-and-Closing Torque Testers for Caps and Knobs
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. For the most accurate performance, the maximum torque you’re applying should fall near the middle of the tester’s torque range. If you accidentally exceed the torque range, these testers have overload protection to prevent damage to the measuring system.
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.

Torque Sensors
Measure and record manually applied torque. These sensors convert torque into an electrical signal that your computer or programmable logic controller (PLC) can read.
Sensors with a PC connection kit include software that plots and analyzes measurements, so you can track highs, lows, and averages over time. If measurements fall outside a certain range, the software can also set off alarms or send you an email. Export your data to Excel, MATLAB, LabVIEW, and other programs for analysis. Connect to a computer or tablet with the included USB cord. Drive adapters let you connect these sensors to the drive of a torque wrench.
Use base plates to mount these sensors to a flat surface for testing.
