ISO/IEC 17025 ACCREDITATION

Our calibration laboratory has been approved for ISO/IEC 17025 accreditation by the ANSI National Accreditation Board (ANAB) for in-house and on-site calibrations.

Achieving ISO/IEC 17025 accreditation shows our commitment to providing the highest quality calibration service, both in our own factory and on-site at your business. Larson Systems Inc.’s customers can have the utmost confidence in the precision and accuracy of every instrument we calibrate, whether it’s one of our own innovative spring testers or another force / length, force or torque measurement instrument.

  1. On-site calibration service is available to this parameter, since on-site conditions are typically more variable than those in the laboratory, larger measurement uncertainties are expected on-site than what is reported on the accredited scope.
