Hardness Tester Calibration Services
Rockwell, Brinell, benchtop or portable — material certs stand on the tester behind them.
ACS Calibration delivers NIST-traceable, audit-ready hardness tester 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.
The Number on the Material Cert
Hardness testers qualify material the rest of the process trusts: incoming steel verified against the mill cert, heat-treat results confirmed before machining, weld zones checked in the field. A tester with worn indenters, drifted load application, or sticky depth measurement quietly re-grades material in whichever direction it pleases.
We verify hardness testers NIST-traceable — load application, depth indication, and response against certified test blocks — documented as-found and as-left, benchtop and portable units alike.
Material-testing benches keep company: durometers for the soft materials, force gauges, and the micrometers measuring what the tester approved — one shipment covers it.
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
