— WHAT IS PRESSURE GAUGE CALIBRATION —
Think of a quality lab that relies on a pressure gauge 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.
Pressure Gauge 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.

— OUR PROCESS —
Gauge received, tagged with job number. Range, make, model noted. Physical condition documented.
Pressure applied at 0%, 25%, 50%, 75%, 100% FS using dead weight tester or reference controller. As-found errors recorded.
Zero and span corrections applied. Pointer alignment checked. Dial glass inspected.
Ascending and descending readings compared. Hysteresis error calculated per ISO 5171.
Post-adjustment readings verified at all 5 points. Uncertainty calculated. Pass/fail recorded.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Pressure gauge certificates accepted by ISO 9001, IATF 16949, GMP/FDA, IBR, PESO, and all audit purposes.
— NON-NABL CALIBRATION —
For routine maintenance or workshops not needing NABL certification — same engineers, same dead weight tester references, lower cost.
All calibrations traceable to NPL via our dead weight tester — only certificate type differs.
Non-NABL gauge jobs faster — ideal for large bulk batches and routine maintenance.
Lower cost than NABL — right for utility gauges, non-critical lines, and site instruments.
Portable dead weight tester at your plant across Gujarat — same team, same quality.
— AREAS WE SERVICE —
Engineers carry portable dead weight testers to your plant. Onsite pressure gauge calibration with zero downtime.
Why Choose Prism
Since 2004, every NABL pressure gauge certificate issued by Prism has been accepted by ISO, IATF, GMP, IBR, PESO, and GPCB auditors — no rejections.
