Cdi Torque 1501MRPH Torque Wrench 20-150 in Lb 1/4 in Drive

Product Description

The CDI TORQUE 1501MRPH is a 1/4 inch drive click-style torque wrench with a dual-scale, dual-direction calibrated mechanism covering 20 to 150 inch-pounds in 1 inch-pound increments. It is designed for precise fastener torque application in HVAC, refrigeration, electrical, plumbing, and general mechanical service work. The wrench meets or exceeds ASME and ISO 6789 standards and ships with an individually serialized certificate of calibration traceable to N.I.S.T. Accuracy is rated at 4 percent clockwise and 6 percent counterclockwise of indicated value from 20 percent to 100 percent of full scale. Licensed tradespeople and service technicians who need a documented, repeatable torque reference will find this tool suited to service calls and bench work alike.

The 1501MRPH is used in residential and light commercial applications wherever controlled fastener torque is required. Common install scenarios include tightening electrical panel terminals, compressor mounting bolts, refrigerant fitting fasteners, and equipment access panel hardware. The 1/4 inch drive accepts standard sockets and is a practical fit for confined service spaces. Quick-release buttons on most configurations allow easy socket swaps on the job.

Key Features

• Individually serialized with N.I.S.T.-traceable certificate of calibration included
• Meets or exceeds ASME and ISO 6789 standards

Compatibility

Designed for use with standard 1/4 inch drive sockets. Suitable for trade service applications requiring documented torque accuracy in the 20 to 150 inch-pound range.

Installation Notes

This tool is used by licensed HVAC technicians, electricians, plumbers, and mechanical service professionals. Before use, verify the wrench setting and confirm the lock ring is engaged. Return the wrench to its lowest setting after each use to preserve spring calibration. Periodic recalibration is recommended per ASME B107.300 guidelines and any applicable jurisdictional maintenance requirements.
