What I would look for
For precision measurement instruments, don't just ask whether a company is "NIST traceable." If your quality system requires accredited calibration, ask whether the specific instrument and measurement range are within the laboratory's ISO/IEC 17025 scope. Also ask for:
As-found and as-left measurements
Measurement uncertainty
NIST/SI traceability
Calibration against the manufacturer's specifications
Adjustment/repair if the instrument is out of tolerance
A certificate suitable for your QMS/audit requirements
On-site versus laboratory calibration and turnaround time
If you tell me what instruments you need calibrated (e.g., micrometers, calipers, torque wrenches, pressure gauges, multimeters, optical equipment, CMMs, balances) and roughly how many, I can narrow this to the most relevant providers and compare their capabilities.
