Proto J6472 Electronic Torque Tester 25-250 In/lb

Product Description

The PROTO J6472 is an electronic torque tester designed to verify and calibrate torque output across a range of 25 to 250 inch-pounds (2.1 to 20.8 foot-pounds). It delivers plus or minus 1% accuracy, making it suitable for use as both a torque meter and a calibration reference tool. The 3/8 inch drive accepts standard sockets and torque tool adapters. Licensed mechanics, calibration technicians, and tool room supervisors rely on this tester to confirm that torque wrenches and drivers are performing within specification before and after use in critical fastening applications.

The J6472 is used in automotive shops, HVAC and refrigeration service environments, industrial maintenance facilities, and tool calibration labs. It is well suited for any trade application where torque wrench accuracy must be verified before tightening fasteners on compressors, flanged fittings, electrical enclosures, or equipment panels. Its electronic readout eliminates the ambiguity of mechanical dial testers and provides a direct digital confirmation of applied torque values.

Key Features

• Torque range of 25 to 250 inch-pounds (2.1 to 20.8 foot-pounds) covers common trade fastening applications
• Plus or minus 1% accuracy supports use as a calibration reference and quality-control instrument
• 3/8 inch drive accepts standard sockets and drive adapters for broad tool compatibility
• Electronic readout provides direct digital torque display, reducing reading error
• Functions as both a torque meter and a torque wrench calibrator in a single unit

Compatibility

Designed to test and calibrate 3/8 inch drive torque wrenches and drivers with output values falling within the 25 to 250 inch-pound range. Compatible with standard square drive torque tools used across automotive, HVAC, plumbing, and industrial maintenance applications.

Installation Notes

No installation is required. This is a benchtop or handheld testing instrument. Secure the tester in a stable position or fixture before applying torque to prevent movement during measurement. Follow the tool manufacturer calibration interval guidelines and applicable shop quality-control procedures when using this device as a calibration reference. Do not exceed the maximum rated torque of 250 inch-pounds to avoid damage to the tester.
