Expert, Precise Torque Calibration Services

What We Do

S. Himmelstein and Company offers the broadest available range of ISO 17025-accredited torque calibration services, from 10 ozf-in to 4 million lbf-in (0.07 Nm to 452,000 Nm). The 4,000,000 lbf-in fixture is one of only three worldwide accredited for calibrations above 1,000,000 lbf-in and has the lowest measurement uncertainty of them all. Our torque calibration equipment includes nine calibration stands that provide optimal measurement uncertainty for the range of transducer being calibrated. Our expertise and specialization make us the ideal provider of torque calibration services in the industry.

Services are offered for torque transducers manufactured by Himmelstein as well as by other manufacturers, including HBM, Honeywell, Lebow, Futek, AKO, Manner, Interface, GIF, Kistler, Lorenz, Sensor Developments, Sensor Data, ETH, Magtrol, Datum, Norbar, PCB and more. ISO 17025-accredited, NIST-traceable calibration certificates are provided with each torque transducer calibration. With our help, you can get the most out of your equipment and enjoy the most efficient environment possible.

The Importance of Torque Transducer Calibration

Because transducers are essential to ensure the accurate operation of torque wrenches, it is crucial to make sure they are properly calibrated. Performing annual testing of your equipment is critical, but it’s just as important to make sure this work is performed by qualified and experienced professionals. The provider you choose should have ISO 17025 accreditation, first and foremost. In addition, you should find out whether or not the company can calibrate within the required torque range of your transducers.

As one of the leaders in torque transducer calibration with accreditation from NVLAP, S. Himmelstein and Company has the expertise and experience needed to handle this highly sensitive operation. To learn more about what we can do for you, get in touch with us today.
