Serving Killeen, TX
Killeen sits in western Bell County, about 68 miles north of Austin, and is the principal city of the Killeen–Temple–Fort Hood metropolitan area. The city is bordered on the north by Fort Hood and on the east by Harker Heights, and is reached by Interstate 14 and U.S. Highway 190 — the Central Texas Expressway — along with State Highway 195 and Spur 172 into the post's main gate. Interstate 35 is 16 miles east at Belton, the county seat. The local economy is built on Fort Hood: the post is headquarters to III Armored Corps and First Army Division West and home to the 1st Cavalry Division and 3rd Cavalry Regiment, and the U.S. Army Operational Test Command runs the Army's operational testing from West Fort Hood. The City of Killeen's 2024 annual financial report lists military defense contractors and related firms as the city's second-largest employer group, at roughly 7,447 people. Tra-Cal supports that work with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Tra-Cal's laboratory is in Gaithersburg, Maryland, and Killeen is far outside our Mid-Atlantic pickup-and-delivery radius, so we do not run a local courier route in Central Texas. We serve the Killeen area through two intake paths instead: prepaid ship-in calibration with a typical five-business-day turnaround, and scheduled onsite visits by Tra-Cal mobile calibration labs, each carrying standards for more than 100 instruments. Both paths carry the same accreditation, NIST traceability, and certificate documentation, with ANSI/NCSL Z540-1 and Z540.3 reporting available for customers audited to AS9100, ISO 13485, ISO 9001, or FDA 21 CFR Part 820.

How Tra-Cal Serves Killeen, TX
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 Killeen-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
-
No. Tra-Cal's ISO/IEC 17025:2017 accredited laboratory is located at 8577 Atlas Drive, Gaithersburg, MD 20877. We serve Killeen, Fort Hood, and the rest of western Bell County from that lab through prepaid ship-in service and scheduled onsite mobile-lab visits. We do not operate a walk-in counter anywhere in Central Texas.
-
Most Killeen-area customers use prepaid ship-in. We send a shipping label, your instruments travel to Gaithersburg, and typical in-lab turnaround is about five business days. For larger consolidated loads, such as a contractor shop supporting Fort Hood, we schedule an onsite visit with a Tra-Cal mobile calibration lab instead. Killeen sits well outside our Mid-Atlantic pickup-and-delivery radius, so we do not run a local courier route there.
-
Yes. Fort Hood is the headquarters of III Armored Corps and First Army Division West and is home to the 1st Cavalry Division and 3rd Cavalry Regiment. The City of Killeen's 2024 annual financial report lists military defense contractors and related firms as the city's second-largest employer group, at roughly 7,447 people. Our ANAB accreditation, NIST-traceable certificates, and ANSI/NCSL Z540-1 and Z540.3 reporting options are built for that documentation environment.
-
We cover RF and microwave, general electronic, temperature and humidity, physical and dimensional, oven and freezer, optical, and timing and frequency. RF and microwave capability is particularly relevant around Fort Hood, where the 69th Air Defense Artillery Brigade, the 11th Signal Brigade, and the 116th and 504th Military Intelligence Brigades operate radar, communications, and signals equipment.
-
The U.S. Army Operational Test Command is headquartered at West Fort Hood and runs the Army's operational testing, a role the post has held since the Test and Experimentation Command era of the 1970s. Test organizations and their supporting contractors need documented, traceable measurement uncertainty. Tra-Cal provides NIST-traceable calibration with full data reporting, performed either at our Gaithersburg lab or onsite by mobile lab.
-

Belton is the Bell County seat and the nearest access to Interstate 35, about 16 miles east of Killeen. Killeen itself is reached by Interstate 14 and U.S. Highway 190, the Central Texas Expressway.
-
Yes. Tra-Cal is accredited to ISO/IEC 17025:2017 by ANAB and supports customers audited to AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820.
