— WHAT IS SURFACE ROUGHNESS TESTER CALIBRATION —
Think of a quality lab that relies on a surface roughness tester for daily measurements. If it has drifted even slightly from its true value, every reading becomes unreliable — leading to defective products, failed audits, or safety risks. Regular calibration is the only way to confirm your instrument is telling the truth.
Surface Roughness Tester calibration means comparing its readings against a NABL-traceable certified reference standard at multiple test points, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.
Compare readings against a NABL-traceable reference standard across the full measurement range.
Adjust or document deviations so your instrument reads within accepted tolerance.
Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.
— INSTRUMENTS COVERED —
Portable & bench-top · All makes (Mitutoyo, Surftest, Taylor Hobson, Zeiss) · ISO 4287 · NABL accredited
Portable surface roughness testers measuring Ra, Rz, and other roughness parameters.
Portable profilometers for surface texture measurement in field and workshop.
Bench-top surface testers with high accuracy for laboratory roughness measurement.
Certified roughness reference specimens for tester calibration and verification.
— OUR PROCESS —
Profilometer received and tagged. Stylus tip radius, pick-up unit, traverse mechanism, and electronic display inspected.
NPL-traceable roughness calibration specimens used to measure as-found Ra and Rz deviation at fine, medium, and coarse levels.
Stylus tip radius measured under optical microscope. Replaced if worn beyond tolerance per ISO 3274. New stylus force verified.
Traverse speed and cut-off wavelength settings verified against calibration. Filter settings checked per ISO 4288.
Post-correction readings on reference specimens at all three roughness levels. Measurement uncertainty calculated per GUM.
NABL CC-2480 certificate issued with as-found/as-left Ra/Rz data, expanded uncertainty (k=2), ISO 4287/4288 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Surface roughness tester certificates accepted by IATF 16949, ISO 9001, and all precision machining and automotive component audit bodies.
— NON-NABL CALIBRATION —
For routine production checks or workshops not requiring NABL certification — same engineers, same reference specimens, lower cost.
All calibrations use NPL-traceable roughness specimens — only the certificate type differs.
Non-NABL profilometer jobs completed quickly — ideal for large machining batches.
Lower cost than NABL — right for workshop instruments and non-critical surface checks.
Ra, Rz, Rq, Rt — all primary surface texture parameters covered by the same specialist team.
— AREAS WE SERVICE —
Engineers carry certified roughness specimens to your machining facility. Onsite profilometer calibration with minimal downtime.
Why Choose Prism
Since 2004, every NABL certificate issued by Prism has been accepted by IATF 16949, ISO 9001, and automotive component audit bodies — no rejections.
