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.
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).

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. 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.

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.
