Durometer Calibration Services
Shore A to Shore D — rubber and plastic hardness starts at a verified indenter and a healthy spring.
ACS Calibration delivers NIST-traceable, audit-ready durometer calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Every certificate is backed by real measurement data, and accredited certificates are available for instruments on our PJLA scope.
Hardness Is a Chain of Small Mechanics
Durometers qualify the soft parts machines depend on: o-rings, seals, gaskets, tire compounds, molded plastics. A Shore reading is really three measurements in a trench coat — indenter geometry, spring force at displacement, and dial or digital indication — and each element drifts with use, drops, and age.
We verify durometers NIST-traceable across those elements with as-found and as-left data documented, Shore A and D scales alike — so incoming-inspection hardness calls and certificate-of-conformance claims stay defensible.
Durometers usually share QC benches with force gauges, dial indicators, and calipers — one shipment covers the bench.
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
