Precision Instruments TC3F175F 1/2" Drive Analog Torque Comparator, 35 to 175 Pound-Feet

Precision Instruments TC3F175F 1/2" Drive Analog Torque Comparator, 35 to 175 Pound-Feet

• Precision Instruments TC3F175F is an analog torque comparator for quick in-house checks of torque wrench output before tools are sent off-site for calibration. It mounts to a stable work surface and compares click or dial wrench readings during controlled testing.
• Features:
  • Accurate within 2% of reading from 20% of full scale to full scale.
  • Integrated exercise adapter and large dial support torque wrench checks before use.
  • Comparator must be securely mounted to a flat, stable surface using all mounting holes in the baseplate.
  • Operates without power requirements.
  • Meets or exceeds GGG-W-686C and ANSI B107.14M specifications.

Precision Instruments was incorporated in 1938 to manufacture torsion bar dial type wrenches. The company operates two buildings with 50,000 square feet in Des Plaines, Illinois, handling machining, polishing, plating, assembly, and calibration on site.

Q: How should the TC3F175F be mounted for use?
A: It must be securely mounted to a flat, stable surface using all mounting holes in the baseplate.

Q: What is the exercise adapter used for?
A: The exercise adapter is used to exercise the torque wrench before testing; the manual recommends applying torque at least three times at roughly 50% of full scale.

Q: Can impact tools be used with this torque comparator?
A: No. The user manual states that using the comparator with impact tools will destroy it.
