S. Himmelstein and Company provides accredited ISO/IEC 17025:2017 torque calibrations from 10 ozf-in to 4,000,000 lbf-in (0.07 Nm to 452 kNm). That's the world's widest range of commercially available accredited calibrations.  Our 4,000,000 lbf-in (452 kNm) stand is one of only four worldwide that are accredited for calibrations above 1,000,000 lbf-in (113 kNm), and it has the lowest uncertainty of any. We have nine accredited stands that provide optimal measurement uncertainty and avoid queuing delays if using fewer stands.  Calibrations are made for Himmelstein transducers as well as those from HBM, Honeywell, Lebow, Futek, AKO, Manner, Magtrol, Interface, GIF, Kistler, Lorenz, ETH, Sensor Developments, Sensor Data, omega, Datum, Norbar, PCB and more. Calibration certificates summarizing results and certifying ISO/IEC 17025:2017 accreditation are always provided.  With our calibration service you get the best results from your torque sensors while complying with international standards.
