— WHAT IS VACUUM GAUGE CALIBRATION —
Think of a quality lab that relies on a vacuum 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.
Vacuum 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 —
Vacuum gauge received, tagged. Range, type (Bourdon/Pirani/Capacitance) noted. Physical condition documented.
Reference vacuum controller/dead weight tester applies 0%, 25%, 50%, 75%, 100% FS vacuum. As-found readings logged.
Zero at atmosphere (0 vacuum). Span set at calibrated vacuum reference. Pointer or display aligned.
Ascending and descending readings at 5 points. Hysteresis calculated. Pirani/thermocouple response verified.
Post-adjustment readings confirm compliance. Expanded uncertainty (k=2) calculated. Pass/fail recorded.
NABL CC-2480 certificate with as-found/as-left vacuum readings, uncertainty, ISO 3529/ISO 5171 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Vacuum gauge certificates accepted by ISO 9001, IATF 16949, GMP/FDA, IBR, PESO, and all audit purposes.
— NON-NABL CALIBRATION —
Routine maintenance calibration without NABL certification — same engineers, same vacuum reference, lower cost.
All calibrations traceable to NPL via vacuum reference standards — only certificate type differs.
Non-NABL vacuum gauge jobs faster — ideal for large bulk batches and routine maintenance.
Lower cost than NABL — right for utility vacuum gauges and non-critical vacuum systems.
Bourdon vacuum gauges calibrated onsite; Pirani/capacitance gauges in-lab. Gujarat-wide.
— AREAS WE SERVICE —
Onsite vacuum gauge calibration across all Gujarat with portable vacuum references.
