Proto J6476 Electronic Torque Tester 300-3000 In/lb

Product Description

The PROTO J6476 is an electronic torque tester designed to measure and verify torque output across a range of 300 to 3,000 inch-pounds (25 to 250 foot-pounds). Built for shop and field calibration work, it delivers plus or minus 1% accuracy, making it suitable for verifying torque wrenches, torque multipliers, and other torque-applying tools. The 1/2 inch drive interface accepts standard drive adapters for broad compatibility with existing tooling. This instrument serves as both an electronic torque meter and a calibrator, supporting quality assurance workflows in automotive, industrial, and mechanical service environments. Weighing 6.16 pounds, it is a bench-capable unit that technicians and tool calibration professionals rely on for traceable torque verification.

The J6476 is suited for use in automotive repair shops, industrial maintenance facilities, and calibration labs where torque tool verification is a routine requirement. It handles mid-to-high torque ranges, covering most 1/2 inch drive wrench applications. Technicians performing preventive maintenance programs or ISO-compliant calibration cycles will find this tester appropriate for documenting torque wrench performance across the full 300 to 3,000 in/lb span.

Installation Notes

This tool is typically operated by calibration technicians or experienced mechanics in a controlled shop or bench environment. Ensure all power sources to any equipment under test are isolated before applying the tester to connected tooling. Follow applicable calibration interval requirements per your quality management program or applicable industry standards. Store the unit in a protective case when not in use to maintain calibration integrity.
