Calibration Services

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 4,000,000 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.

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 calibration.

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.
