FAQ

Frequently Asked Questions About Calibration Services

What is ISO/IEC 17025 accredited calibration?
ISO/IEC 17025 is the international standard for testing and calibration laboratory competence. An accredited calibration — like those performed by Techmaster Electronics under our A2LA scope — is independently verified for measurement traceability, documented uncertainty, and technical competence, which most quality systems (ISO 9001, AS9100, ISO 13485) require for critical instruments.
How often should test equipment be calibrated?
Most manufacturers recommend a 12-month calibration interval, but the right interval depends on usage, environment, stability history, and your quality system requirements. Techmaster can help you set data-driven calibration intervals and manages recall schedules automatically through our customer portal.
Do you offer on-site calibration?
Yes. Our technicians perform on-site calibration at your facility for large instrument fleets or equipment that cannot be shipped, in addition to in-lab service at our five U.S. laboratories and free local pickup and delivery routes.
What is your standard turnaround time?
Standard turnaround is 5–7 business days from receipt. Expedited service is available when you need instruments back faster, and our logistics team offers free local pickup and delivery around each lab.
Are your calibrations NIST-traceable?
Yes. All calibrations performed by Techmaster Electronics are traceable to the National Institute of Standards and Technology (NIST) or other national metrology institutes, with documented measurement uncertainty on accredited certificates.
Where are your calibration labs located?
Techmaster Electronics operates ISO/IEC 17025 accredited calibration laboratories in Vista CA, Santa Clara CA, San Antonio TX, Orlando FL, and Holly Springs NC, serving customers across the entire United States.
