Great Lakes Calibration is ISO/IEC 17025 Accredited to Perform Dynamic Force Verification in Accordance with ASTM E-467 and NASM 1312

Utilizing custom designed and engineered data acquisition electronic and custom built strain gauged dynamometers, Great Lakes Calibration can perform a dynamic force verification of your fatigue testing machines. Our state of the art data acquisition system allows us to record the output of the strain gauges dynamometer at a rate of 30-kHz allowing us to perform dynamic verifications at cycle frequencies of up to 60-Hz. Having this capability makes Great Lakes Calibration one of very few calibration companies in the USA that can perform an accredited dynamic force verification.

 

 

Retrofit and Electronic/Software Upgrades for Tensile Machines and other Force Testing Equipment

 Great Lakes Calibration can retrofit your tensile machine with new state of the art electronics and software packages from Admet. The retrofit packages are custom tailored to your specific needs. Retrofitting your tensile machines is a great way to extend the life of mechanical or hydraulic load frames. The load frame will last a very long time and will certainly outlast the electronics. With an Admet retrofit package, we can extend the life of your tensile frame by replacing the old and outdated electronics with a new display system and software programs. We can even convert a manually controlled machine to a fully servo controlled computerized system.

 

All calibration services offered by Great Lakes Calibration are performed in accordance with ISO/IEC 17025:2005, ANSI/NCSL Z540, and ISO 9000 requirements. Calibration procedures are based on the requirements of international standards such as ASTM, ASME, AMS, ISO, NIST, ASHTO, and many others.
