Serving Longmont, CO
Longmont sits on St. Vrain Creek in northeastern Boulder County, with US-287 running through town as Main Street, the Diagonal Highway angling southwest to Boulder, CO-66 crossing the north side, and I-25 five miles east. For a city of 99,000 it carries a deep engineering base: Redwire builds and tests deployable space structures and RF payloads, Maxar Technologies runs satellite and Earth-observation programs, Seagate Technology's storage campus is the largest private employer at 1,400 people, EnerSys develops stored-energy systems, and the FAA operates the Denver Air Route Traffic Control Center here. Precision optics and photonics manufacturers surround them. We offer prepaid ship-in calibration with a five-business-day turnaround or onsite calibration appointments, ANAB-accredited to ISO/IEC 17025:2017, NIST-traceable, with certificates supporting AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820.

How Tra-Cal Serves Longmont, CO
In-Lab Calibration:
Send your equipment to our ANAB-accredited ISO/IEC 17025:2017 laboratory with prepaid inbound and return shipping. Calibration is performed in a climate-controlled environment against documented procedures, with traceability through NIST. Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.
Onsite Calibration:
Our metrologists travel to Longmont-area facilities for fixed assets, large inventories, and instruments that should not be moved. Calibration is performed in a controlled environment at your site on a scheduled appointment, with the same accreditation, NIST traceability, and documentation as in-lab service.
Frequently Asked Questions
-
Yes. Longmont sits well outside our Mid-Atlantic pickup and delivery radius, so we support the St. Vrain Valley through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. The same ISO/IEC 17025:2017 accreditation, NIST-traceable standards, and certificate format apply regardless of intake method.
-

-
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.
