This new technology offers quick, accurate and affordable way to check your torque wrenches as easy as 1-2-3, taking only a few minutes. Simply mount torque checker close to each department where torque wrenches are used,attach the torque wrench to the checker and the accuracy will be displayed on the digital screen.

Features of this new digital torque checker:

  • +- 1% Accuracy
  • 1/2″ dr. 25-250 ft.lbs.
  • Runs on 3 “AA” batteries
  • Includes 3/8″ adapter
  • Features excerciser socket
  • Adjustable sleep timer

The video below will show you the benefits and how to use the Snap-on torque checker which is the same as the CDI Snap-on Industrial brands DTC torque checker.





Robb Precision Tool Services Visits the Largest Private Labeled Torque Manufacture in the World: CDI Torque Products

As the demand for accuracy increases, at an outstanding rate, so does the technology in Torque Products.  To better help their customers meet this demand; Robb Precision visited one of the pioneers in the development of digital torque measurement systems, CDI, a Snap-on owned company.

The technicians received hands on training and education on the new line of Electronic Torque Wrenches and the cutting edge DTC Torque checker.

An exciting new torque tool is the portable DTC Torque Checker. This torque checker is designed to be affordable and enables torque wrench users to conveniently and simply check mechanical and digital torque wrenches for accuracy between calibration cycles, close to where they are used and stored. The DTC features 3 modes of operation, runs on three AA batteries and has a +/- accuracy. Other features include first peak, peak hold and tracking, ft/inch lb and NM and many other options.

The technicians also received training on the state-of-the art digital torque wrenches. These torque wrenches offer the most accurate and fastest way to tighten fasteners in a sequence, with audible beep and vibration that alert you when target torque is achieved.  Most of these torque wrenches have an easy-to-use plug and play software solution and highly programmable features.

Robert Robb, owner “Continued education is essential to meet the demands for increased accuracy and performance. I have had a relationship with CDI, a Snap on owned company for 20 years and became the first stocking distributor of CDI torque products in the United States in 2003. CDI is the largest manufacturer of Torque products in the world and I believe are the best in the industry.”
