In-Lab & Onsite Calibration Services in St. Louis, MO

Yes. Eastern Missouri sits well outside our Mid-Atlantic pickup and delivery radius, so we support St. Louis and the surrounding metro through two intake paths: prepaid ship-in service with a typical five-business-day turnaround, and scheduled onsite calibration appointments at your facility. The same ISO/IEC 17025:2017 accreditation, NIST-traceable standards, and certificate format apply regardless of intake method.

Yes. Tra-Cal maintains ISO/IEC 17025:2017 accreditation. ANSI/NCSL Z540-1 and Z540.3 conformance is also available. The current scope of accreditation is published on the Tra-Cal Certificate of Accreditation page.

Standard turnaround for in-lab calibration is approximately five business days from receipt of the instrument. Expedited turnaround is available on request and depends on instrument type, parameter scope, and current lab volume.

Each calibration certificate documents traceability through NIST, includes as-found and as-left data where applicable, lists the standards used, the calibration procedure reference, environmental conditions, and the technician.

Yes. Our mobile laboratories travel to St. Louis-area sites for fixed assets, large inventories, and instruments that should not be transported, including production and test equipment in the aerospace corridor around Lambert and process instrumentation at plants along the Mississippi. A scheduled appointment is set with your team, and calibration is performed in a controlled environment at your facility with full documentation.

A packaging guide is provided when you request a quote. In general, instruments should be powered down, accessories included where required for calibration, and packed with appropriate cushioning. A prepaid shipping label is available for qualifying customers.
