— WHAT IS MICROMETER CALIBRATION —
A micrometer that reads 0.01mm high on every shaft it measures will pass hundreds of out-of-tolerance parts before anyone notices. Micrometer calibration catches zero drift, anvil wear, and spindle errors — and documents them in an NABL certificate accepted by every quality auditor.
Check
Measured against NPL-traceable Grade-A gauge blocks at 5+ points across full range. As-found data recorded.
Correct
Zero adjustment, anvil flatness check, thimble backlash. Correction table issued if needed.
Certify
NABL CC-2480 certificate with as-found/as-left data — accepted by ISO 9001 & IATF.
— INSTRUMENTS COVERED —
All 5 micrometer types · All makes (Mitutoyo, Baker, Insize, Mahr, Starrett) · NABL accredited
Outside micrometers for precision external diameter and thickness measurement.
Inside micrometers for precise internal bore and groove measurement.
Depth micrometers for measuring depths of slots, holes, and steps.
Bench micrometers for high-accuracy dimensional measurement on a stand.
Disc micrometers with disc-type anvil for measuring grooves and recesses.
— OUR PROCESS —
Micrometer received, tagged, incoming condition documented — spindle condition, thimble action, zero check.
Spindle and anvil cleaned, zero error noted (as-found). Thimble movement and ratchet/friction stop checked.
Measured against NPL-traceable Grade-A gauge blocks at 5+ points. All deviations recorded.
Zero adjustment performed. Correction table issued for fixed-reading instruments.
Post-adjustment readings verified at all calibration points. Uncertainty calculated per ISO/IEC 17025.
NABL CC-2480 certificate with as-found/as-left data, uncertainty (k=2), ISO 3611 traceability.
— STANDARDS & COMPLIANCE —
Every micrometer calibration follows documented ISO 3611 and NPL procedures — accepted by ISO 9001, IATF 16949, BIS, and all audit bodies.

Gauges & Measuring Instruments
Prism holds NABL CC-2480 under ISO/IEC 17025:2017, recognized under the ILAC MRA agreement. Our micrometer calibration certificates are valid for ISO 9001, IATF 16949, BIS, and all audit purposes.
— NON-NABL CALIBRATION —
For routine maintenance, bulk calibration, or workshops not needing NABL certification — Prism offers cost-effective non-NABL micrometer calibration with the same trained engineers and traceable references.
All non-NABL jobs use the same NPL-traceable gauge blocks — only the certificate type differs.
Non-NABL micrometer jobs completed faster — ideal for urgent maintenance or large bulk batches.
Priced lower than NABL — right choice for internal checks and non-audit use cases.
Available at our Ahmedabad lab and as onsite service across Gujarat — same team, same quality.
— AREAS WE SERVICE —
NABL-certified engineers travel to your facility with portable gauge block sets — calibrate 50+ micrometers per day onsite, zero downtime.
Why Choose Prism
Since 2004, every NABL micrometer certificate issued by Prism has been accepted by ISO, IATF, BIS, FDA, and GPCB auditors — no rejections, no rework.
