Calibration Services

Expert, Precise Torque Calibration Services

What We Do

S. Himmelstein and Company provides accredited ISO/IEC 17025:2017 calibrations  from 10 ozf-in to 4 million lbf-in (0.07 Nm to 452,000 Nm). The 4,000,000 lbf-in 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 measurement 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.

Our Accreditation

Himmelstein’s Torque Calibration Laboratory is accredited by NVLAP, an arm of the NIST, lab code 200487-0. Select the links below for a copy of the NVLAP Certificate and Accreditation Scope.

Certificates of Conformance are available upon request from the factory.

The Importance of Torque Transducer Calibration

The only valid way to verify operation and efficiency of motors, generators, compressors, pumps, transmissions and virtually any rotating machine is to accurately evaluate them when new and periodically verify performance thereafter. That can only be done with a properly sized and calibrated Torque transducer.  As a leader in torque calibration, sensor design and manufacture Himmelstein has the expertise and experience to correctly and expeditiously calibrate your torque sensors.  To learn more, call today (1-800-MEASURE).
