Outside Micrometer Calibration Services
0–1 inch, ten-thousandths at stake — the outside mic is the shop’s precision benchmark.
ACS Calibration delivers NIST-traceable, audit-ready outside micrometer calibration, 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.
The Standard Everyone Reaches For
The outside micrometer is the reference handtool — the one used to settle arguments the calipers started. That reputation is earned mechanically: a precision-ground thread, lapped carbide anvils, a ratchet for consistent force. Every one of those elements wears, and wear at the anvil faces — the exact spot every measurement touches — is where accuracy quietly leaves.
We calibrate outside micrometers against gage blocks at multiple points through the range, 0.05 to 6 inches accredited, documenting as-found and as-left readings so your uncertainty budget rests on data instead of assumption.
Interchangeable-anvil and large-frame mics are covered along with digital models and the rest of the micrometer family — and if your inspection bench includes height gages and indicators, one shipment covers it all.
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
Why Companies Choose ACS for Outside Micrometer Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Calipers, micrometers, height gages, indicators, pin gages, and feeler gages are on our ISO/IEC 17025 accredited dimensional scope — accredited certificates available whenever your quality system requires them.
4–6 Business Day Typical Turnaround
Keep production moving. Most instruments are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your instruments in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
