In-Lab & Onsite Calibration Services in California, MD

Yes. Tra-Cal's ISO/IEC 17025:2017 accredited laboratory is at 8577 Atlas Drive in Gaithersburg, MD, about a two-hour drive northwest of St. Mary's County. The MD-235 corridor is squarely inside our Mid-Atlantic service region, so we support engineering offices, labs, and hangars in California with onsite mobile-lab visits, scheduled pickup and delivery, and prepaid ship-in. We do not maintain a separate office in California.

Yes. Tra-Cal is ISO/IEC 17025:2017 accredited by ANAB, with a scope covering RF and microwave, electronic, temperature and humidity, physical and dimensional, oven and freezer, optical, and timing and frequency measurements. Our procedures reference ANSI/NCSL Z540-1 and Z540.3, which matters for St. Mary's County contractors working to Navy and NAVAIR data requirements as well as AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems. The current scope of accreditation is published on the Tra-Cal Certificate of Accreditation page.

Standard in-lab turnaround is approximately five business days from receipt. Because California sits inside our pickup and delivery radius, St. Mary's County accounts can hand equipment to a Tra-Cal driver rather than a carrier, which usually shortens effective downtime. Expedited handling is available on request when a test event or flight schedule depends on it, and depends on instrument type, parameter scope, and current lab volume.

Yes. Each calibration certificate documents traceability through NIST, includes as-found and as-left data where applicable, and lists the reference standards used, the calibration procedure reference, measurement uncertainty, environmental conditions, and the technician. That is the level of documentation quality teams supporting government contracts in St. Mary's County and AS9100 registrars expect to see during audits and program reviews.

California is the commercial heart of the MD-235 technology corridor in St. Mary's County. Tra-Cal supports the engineering, systems-integration, and test-support contractors clustered in Wildewood Technology Park on Wildwood Tech Parkway; research teams at the University System of Maryland at Southern Maryland SMART Building and the UMD MATRIX Lab on Airport Road; aviation maintenance and avionics shops at Captain Walter Francis Duke Regional Airport; and county facilities, healthcare providers, and industrial contractors along Three Notch Road.

Yes. California is within our onsite mobile-lab territory. Each mobile lab carries more than 100 reference instruments, so RF, electrical, temperature, pressure, and dimensional work can be completed in your lab, hangar, or integration bay without moving assets. That suits secured spaces and bench setups that cannot be broken down and shipped. Appointments are scheduled with your team and performed with the same accreditation, NIST traceability, and documentation as in-lab service.

Request a prepaid shipping label from your account manager, then list each asset with manufacturer, model, serial number, and any special test requirements. Instruments should be powered down, and the cables, probes, and adapters that form part of the measurement path should travel with the unit so the chain can be characterized together. Pack in the original case or double-box with appropriate cushioning and anti-static wrap, and note any intervals or tolerances that must be honored. St. Mary's County accounts can substitute a scheduled pickup for the carrier.

Yes. Tra-Cal maintains asset databases covering calibration intervals, due dates, historical certificates, and automated recall notices, and assigns a dedicated account manager to each account. That is useful for St. Mary's County contractors tracking instruments across several leased suites, labs, and field-test locations under different contract numbers.
