Cdi 2502MRPH Micrometer Ratchet Torque Wrench

Product Description

The CDI 2502MRPH is a micrometer-type ratchet head torque wrench designed for precision fastener work in HVAC, plumbing, electrical, and mechanical service applications. It measures torque in foot-pounds, inch-pounds, and Newton meters, with a clockwise range up to 250 inch-pounds (approximately 28.2 Nm) and a maximum of 70 Nm in the full dual-scale range. The wrench features an ergonomic adjustable clicker handle and a quick-release button for fast socket changes. Calibration is certified to ASME and ISO 6789 standards, making it suitable for documented service work. Overall length is 11 inches and weight is 1.41 pounds.

This torque wrench is well suited for residential and light commercial service calls where precise fastener torque is required. Typical applications include tightening compressor mounting hardware, condensing unit panels, electrical enclosure fasteners, and plumbing connections requiring controlled torque. The dual clockwise and counterclockwise rotation capability allows use in confined access situations where fastener orientation varies. Laser-marked scales on the micrometer barrel allow fast, accurate readings without additional tools.

Key Features

• Dual-scale measurement: foot-pounds, inch-pounds, and Newton meters on a single wrench
• Clockwise accuracy rated at 4 percent; counterclockwise accuracy rated at 6 percent
• Calibration certified to ASME and ISO 6789 standards
• Clockwise and counterclockwise rotation for versatile access in tight spaces
• Positive lock mechanism prevents accidental setting changes during use
• Easy-to-read laser-marked scales and ergonomic micrometer-style handle

Compatibility

Designed as a general-purpose micrometer ratchet head torque wrench suitable for trade service applications requiring calibrated torque measurement in foot-pound, inch-pound, or Newton meter ranges up to 70 Nm.

Installation Notes

This tool is installed and used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Before use, verify the torque setting is locked at the desired value using the positive lock mechanism. Store the wrench at or below its minimum torque setting after each use to preserve the internal spring mechanism and maintain calibration accuracy. Recalibration should be performed per ASME and ISO 6789 service intervals or any time the wrench has been dropped or subjected to shock loading.
