With over 35 years of experience, our technicians have provided precise calibration, instrument repair, and metrology database management to a diverse range of industries across the Milpitas area.
Located in Gaithersburg, MD, our calibration laboratory—accredited to ISO/IEC 17025:2017, ANSI Z540-1, and Z540.3 standards—adheres to strict quality protocols.

Each calibration is accompanied by a certificate that confirms compliance with the rigorous standards set by the National Institute of Standards and Technology (NIST).
Serving Milpitas, CA
Milpitas occupies the northeastern corner of the Santa Clara Valley, wedged between I-880 and I-680 at the point where State Route 237 begins its run west toward Sunnyvale and Mountain View. For a city of roughly 80,000 residents it carries an unusual concentration of measurement-intensive industry. KLA builds semiconductor process-control and yield-management systems that are metrology instruments in their own right. Lumentum and Viavi Solutions, the two companies that emerged from JDSU, keep optical component and network test work here. Analog and power semiconductor operations trace back to Linear Technology, Intersil, and IXYS, contract manufacturing runs through Flex, and Western Digital, Cisco, Renesas, Infineon, and Teledyne all hold offices in town. Medical device and diagnostics work adds another layer through Varian Medical Systems, LifeScan, and Johnson & Johnson Vision. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Milpitas sits well outside our Mid-Atlantic pickup radius, we serve the northeastern Santa Clara Valley through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Each calibration is performed against documented procedures, traced through NIST, and accompanied by an audit-ready certificate that supports AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.

How Tra-Cal Serves Milpitas, CA
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 Milpitas-area facilities for fixed assets, large instrument inventories, and equipment that should not leave a cleanroom or a production floor. 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 Milpitas two ways: onsite calibration performed at your facility by our mobile lab technicians, and prepaid ship-in service to Gaithersburg with a typical five-business-day turnaround. We do not operate a walk-in counter in Santa Clara County.
-
Milpitas is outside our Mid-Atlantic pickup and delivery radius, so most customers in the Milpitas area use prepaid ship-in. We send packaging and a prepaid label, your instruments travel to Gaithersburg, and turnaround in the lab is typically about five business days. Certificates are issued electronically as soon as work is complete.
-
Yes. RF and microwave is one of our core disciplines, which matters in a city built around optical networking, semiconductor process control, and analog silicon. We handle signal generators, spectrum and network analyzers, power meters and sensors, attenuators, noise sources, and frequency counters, with NIST-traceable results.
-
Yes. Tra-Cal is accredited to ISO/IEC 17025:2017 by ANAB, and our measurements are traceable to NIST. We reference ANSI/NCSL Z540-1 and Z540.3 where a customer's quality system calls for it, and our certificates are written to support AS9100, ISO 9001, ISO 13485, and FDA 21 CFR Part 820 audits.
-
Yes. The corridor around Milpitas includes medical device and diagnostics operations, and our documentation package is built for ISO 13485 and FDA 21 CFR Part 820 environments. That includes as-found and as-left data, uncertainty statements, and pass/fail determinations against your stated tolerances.
-
Each Tra-Cal mobile lab carries more than 100 reference instruments, which lets a technician cover electronic, temperature and humidity, physical and dimensional, timing and frequency, and much RF work without removing assets from your floor. Items needing deeper capability are flagged onsite and routed to Gaithersburg.
-
Yes. Oven, freezer, and chamber mapping is a standing capability and is normally performed onsite, since these units are rarely practical to ship. We profile the working volume with a multi-point sensor array and issue a report showing uniformity and stability against your acceptance criteria.
-
We repair instruments from more than 100 manufacturers in-house, so a failed unit does not have to make a second trip. Your dedicated account manager contacts you with findings and an estimate before any repair work begins, and we can also quote replacement equipment through our sales group.
