Depth Gage Calibration Services
Counterbores, keyways, shoulders — depth is the dimension measured blind.
ACS Calibration delivers NIST-traceable, audit-ready depth gage services, available at the ACS central lab or directly on-site at facilities across the Southeast. Calipers, micrometers, height gages, and indicators are all on our accredited dimensional scope, so ISO/IEC 17025 accredited certificates are available on request.
Measuring What You Can’t See
Depth gages — micrometer, vernier, and dial-based — measure features the eye can’t follow: hole depths, counterbores, slots, shoulder steps. The base that squares the measurement wears at its contact edges, and rod-change designs add stack-up error every time rods swap.
We calibrate depth gages against gage blocks and reference standards under our accredited dimensional scope, with as-found and as-left readings. The micrometers and calipers covering the same prints belong on the same cycle.
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
