We now calibrate indicating torque transfer wrenches according to DKD-R 3-7 within a measuring range of 5 to 2,000 N·m, achieving an exceptionally low measurement uncertainty of 0.02% for the calibration torque. This makes our calibration laboratory one of the top three in Germany to offer this level of precision.

Precision at the highest level
Torque transfer wrenches are specialized devices that measure torque as the product of force and lever arm. Thanks to their design, they deliver reliable results even when lateral forces or bending moments are present. This allows torque wrench calibration devices, which are important in industry, to be tested under realistic conditions, including the typical range of variation in lateral forces and bending moments.

"By expanding the measuring range from 5 N·m to 2,000 N·m, we offer our customers broader and more precise calibration options that are traceable, efficient, and have minimal measurement uncertainty," explains Daniel Schwind, Head of the Calibration Laboratory at GTM.

Everything from a single source
Our expansion is based on close collaboration between our product management team and our calibration experts. For our customers, this means a significantly broader range of services. They will not only receive top-tier torque transfer wrenches, but also have the option of having them professionally tested in our accredited GTM calibration laboratory quickly, safely, and reliably.

The advantages for our customers:

• Everything from a single source: development, consulting, manufacturing, and calibration
• Efficiency: shorter distances, fast processing, and close internal coordination
• Quality: highest precision according to internationally recognized standards
• Planning reliability: stable processes, reliable delivery times, and long availability.

With the combination of best-in-class torque transfer wrenches and accredited calibration in our own laboratory, we offer our customers a complete solution that saves time and builds trust.
