Your Calibration Certificate Is Only as Good as the Lab Behind It.
System Scale has been employee-owned since 1995. Our calibration labs are not a business line waiting to be sold off. The accreditation, the standards, and the people who maintain them stay put.
Continuity. The techs who calibrate your equipment know your operation and stay with it, instead of rotating through a dispatch queue.
Consistency. Your calibration history and the standards it’s measured against do not change hands when we do not get acquired.
Independence. We are not building to sell. Your audit trail is not a line item in someone else’s acquisition.
ISO/IEC 17025-Accredited Calibration
ISO/IEC 17025 is the international standard specifying the competence requirements for testing and calibration laboratories. System Scale is accredited to ISO/IEC 17025:2017 by the ANSI National Accreditation Board (ANAB), and every certificate we issue is NIST-traceable. View our Scope & Certificate of Accreditation, or read our plain-language guide to what accreditation actually means.
Why Calibrate With System Scale?
You get exactly what you need, quickly and accurately. Our accredited labs and advanced technology deliver the strength of a large provider, while your local System Scale office delivers a fast, familiar response. Our cloud-based asset management tool, CalVault, keeps your calibration records secure and audit ready.
Full-Scope Coverage, Everywhere
Every System Scale office can get you accredited calibration beyond scales and balances. Ship equipment through our nationwide mail-in service to one of our multiple dedicated calibration labs, or schedule an on-site visit: our dedicated lab teams travel, and a growing bench of hybrid and remote technicians extends that coverage across our footprint. However your equipment reaches us, it comes back with the same ISO/IEC 17025 accredited certificate.

Why Are Calibration Services Important?
Regular calibration from an accredited lab ensures your test equipment provides consistent, accurate results. Key benefits include:
- Ensures measurement accuracy. Confirms your instruments deliver precise, reliable readings.
- Maintains regulatory compliance. Meets industry standards and certification requirements.
- Reduces equipment downtime. Identifies issues before they cause failures.
- Supports audit readiness. Provides documented proof of equipment accuracy.
Calibration is not a one-and-done service. Equipment should be recalibrated on a regular schedule, and also:
- Before and after a critical test requiring precise results.
- When your equipment is damaged or needs to be restored.
ISO/IEC 17025 accreditation means a calibration laboratory has been independently verified to meet international standards for technical competence, quality management, and the ability to produce accurate, reliable results.
Calibration frequency depends on equipment type, usage, and industry requirements. Most instruments should be calibrated annually, though critical or high-use equipment may need more frequent calibration.
NIST traceability means a calibration result can be traced through an unbroken chain of comparisons back to standards maintained by the National Institute of Standards and Technology, ensuring accuracy and consistency.
Every System Scale location is ISO/IEC 17025 accredited for scale and balance calibration. Our dedicated calibration labs carry a broader scope covering dimensional metrology, electrical measurement, force, pressure, and thermodynamic parameters.
