How Tra-Cal Serves Gaithersburg, MD
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 Gaithersburg facilities for fixed assets, large inventories, and instruments that should not be moved.
