Electronic Torque Tester 1/4 Inch Drive 5-50 in-lbs - Armstrong

The Armstrong 64-623 Electronic Torque Tester is a precise instrument engineered for professional automotive and industrial settings, ensuring accurate and repeatable verification of torque wrenches and screwdrivers. This 1/4 inch drive tester is designed for critical low-torque applications, providing reliable calibration and spot-checking for tools ranging from 5 to 50 in-lbs, essential for maintaining accuracy in sensitive engine components, electronic assemblies, and light manufacturing tasks. It is built to be a sturdy, compact, and cost-efficient tester.

Key Features

• Accurate Torque Verification: Offers electronic torque verification within a 5–50 in-lbs range, suitable for precise calibration of low-torque click, dial, and electronic torque wrenches and screwdrivers used in delicate applications. The broad accuracy range extends from 10% to 100% of full scale.
• Multiple Test Modes: Incorporates Track, Peak, and First Peak modes, enabling technicians to monitor live torque, capture maximum applied torque, or identify the initial click point of mechanical wrenches for thorough quality checks.
• Intuitive Go/No-Go Feedback: Simplifies the verification process with clear three-color LED indicators (yellow for under target, green for within target, red for over target) and an audible signal, allowing for immediate confirmation of whether tools are within specified tolerances.
• Bi-directional Measurement: Capable of accurately measuring both clockwise and counterclockwise torque, providing versatility for various fastener applications, including standard and reverse-thread configurations.
• Durable Construction: Built with an all-steel housing and a robust rotary neck, this unit is designed for longevity and reliability in demanding shop environments, supporting both bench and wall-mounted installations.

Applications

• Verifying and documenting torque wrench calibration in professional automotive service bays.
• Checking the accuracy of torque screwdrivers for instrument clusters, electronic components, and interior trim work.
• Performing quality control checks in light manufacturing and assembly lines requiring precise torque application.
• Confirming torque settings on small engine, powersports, and transmission sub-assemblies.
• Can be utilized with non-impacting power tools when paired with an appropriate joint rate simulator.
