Starrett Calibration Services
A century and a half of precision toolmaking — kept precise by regular calibration.
ACS Calibration delivers NIST-traceable, audit-ready calibration for Starrett instruments, available at the ACS central lab or directly on-site at facilities across the Southeast — with ISO/IEC 17025 accredited certificates available on request for instruments on our accredited scope.
Starrett Equipment, Calibrated With Data
L.S. Starrett tools earn multi-decade service lives, which is exactly why they need documented calibration: a 30-year-old Starrett micrometer can still be a precision instrument or a worn one, and only data tells you which. We see Starrett micrometers, calipers, feeler gages, and dial indicators constantly — the second most common dimensional brand in our lab.
We calibrate Starrett instruments against gage blocks under our accredited dimensional scope with as-found and as-left readings per point — wear trends documented so grand-old tools stay defensible instruments instead of heirlooms with opinions.
ACS Calibration is an independent ISO/IEC 17025 accredited calibration laboratory. We are not affiliated with, sponsored by, or endorsed by Starrett; brand names are used solely to identify equipment we service.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
