Proto J6470 Electronic Torque Tester 5 to 50 In/lb

Product Description

The PROTO J6470 is an electronic torque tester designed for verifying and calibrating torque output on hand tools and power tools in shop and field environments. It measures torque in the range of 5 to 50 inch-pounds, with a 1/4 inch drive interface and a stated accuracy of plus or minus 1 percent. The J6470 functions as both a torque meter and a calibrator, making it a practical instrument for quality control checks on torque wrenches and drivers. Technicians in HVAC, plumbing, electrical, and general mechanical trades rely on tools like this to confirm that fasteners are driven to specification and that their torque instruments remain within calibration tolerance.

The J6470 is suited for use in service shops, tool rooms, and job-site calibration stations. Its lower range of 5 inch-pounds and upper range of 50 inch-pounds covers the torque output typical of 1/4 inch drive hand tools and small power drivers. It is appropriate wherever tradespeople need to verify tool accuracy before use or document torque readings for quality assurance records.

Key Features

• Torque range of 5 to 50 inch-pounds (0.42 to 4.17 foot-pounds)
• Plus or minus 1 percent accuracy for reliable calibration verification
• 1/4 inch drive interface compatible with standard hand tools and power drivers
• Functions as both an electronic torque meter and a calibrator
• Compact single-unit design for bench or portable use

Compatibility

Designed as an OEM-style torque testing instrument for use with 1/4 inch drive torque wrenches, screwdrivers, and power drivers operating within the 5 to 50 inch-pound range.

Installation Notes

The J6470 is a benchtop or portable test instrument, not a permanently installed component. Calibration and torque verification work should be performed by a qualified technician following the tool manufacturer guidelines and any applicable shop quality control procedures. Ensure the drive connection is fully seated before applying torque loads. Do not exceed the 50 inch-pound maximum rated capacity of the instrument.
