— WHAT IS HEIGHT GAUGE CALIBRATION —
A height gauge with a drifted zero datum will give wrong vertical dimensions on every machined part it inspects. Height gauge calibration verifies linearity, beam squareness, and zero datum against NPL-traceable gauge blocks on a Grade-A surface plate.
Check
Measured against NPL-traceable gauge blocks on Grade-A surface plate at 5+ points. As-found data recorded.
Correct
Zero datum reset, beam squareness checked. Snap gauge GO/NO-GO dimensions verified against masters.
Certify
NABL CC-2480 certificate with as-found/as-left data — accepted by ISO 9001 & IATF.
— INSTRUMENTS COVERED —
All 5 gauge types · All makes (Mitutoyo, Baker, Insize, Starrett) · NABL accredited
Analog vernier height gauges for scribing and height measurement on surface plates.
Digital height gauges with electronic display for precision height measurement.
Fixed snap gauges (Go/No-Go) for rapid diameter acceptance testing.
Adjustable snap gauges for flexible diameter tolerance checking.
Caliper checkers for verification of caliper calibration and accuracy.
— OUR PROCESS —
Gauge received, tagged, condition documented — beam condition, scribing needle, digital readout.
Surface plate datum verified, zero error noted (as-found). Beam squareness and column movement checked.
Measured against NPL-traceable gauge blocks on Grade-A surface plate at 5+ points. All deviations recorded.
Zero adjustment performed. Beam straightness corrected where applicable. Correction table issued.
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 13225 / ISO 1938 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Our height gauge and snap gauge calibration certificates are valid for ISO 9001, IATF 16949, BIS, and all audit purposes.
— NON-NABL CALIBRATION —
For routine maintenance or workshops not needing NABL certification — cost-effective non-NABL calibration with the same engineers and traceable references.
All non-NABL jobs use NPL-traceable gauge blocks — only the certificate type differs.
Non-NABL 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 onsite across Gujarat — same team, same quality.
— AREAS WE SERVICE —
NABL-certified engineers travel to your facility with portable gauge block sets and surface plates — zero downtime.
Why Choose Prism
Since 2004, every NABL height gauge and snap gauge certificate issued by Prism has been accepted by ISO, IATF, BIS, FDA, and GPCB auditors — no rejections, no rework.
