Cdi 1503MFRMH Micrometer Torque Wrench 34-197 Nm

Product Description

The CDI 1503MFRMH is a micrometer-style torque wrench designed for professional technicians who require precise, repeatable torque application in both clockwise and counterclockwise directions. It covers a range of 34 to 197 Newton-meters (Nm) with a fine graduation of 1.4 Nm, making it suitable for critical fastening tasks across HVAC, mechanical, and general trade service work. The wrench measures 19 inches overall length and features laser-marked dual-scale graduations for fast, accurate readings. A positive lock mechanism and quick-release button support efficient operation in field and shop environments. Calibration is certified at the factory.

The 1503MFRMH is well suited for residential and commercial service applications where accurate torque values must be met and documented. Typical use cases include equipment assembly, compressor service, refrigerant line fittings, and any fastening operation requiring verified torque within the 34 to 197 Nm range. The dual-scale, bidirectional design makes it practical for technicians working in tight or awkward orientations where both clockwise and counterclockwise torque must be applied and confirmed.

Installation Notes

This wrench is intended for use by trained technicians familiar with torque specification requirements for the equipment being serviced. Always set the torque value before applying the wrench and engage the positive lock after setting. Store the wrench at its minimum torque setting when not in use to preserve internal spring calibration. Recalibrate at regular intervals per your shop quality program or applicable service standards.
