— WHAT IS MULTIMETER CALIBRATION —
Think of a quality lab that relies on a multimeter 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.
Multimeter 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.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. DMM multi-function calibration certificates accepted by ISO 9001, pharma, IATF 16949, and all industry QMS audit bodies.
— NON-NABL CALIBRATION —
For routine maintenance, bulk calibration, or internal QC checks where a full NABL certificate is not mandatory — Prism offers cost-effective non-NABL calibration using the same NABL-traceable reference standards and trained engineers.
All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.
Without full NABL documentation, instruments return faster — ideal for urgent production schedules.
Non-NABL calibration costs less — practical for large batches or routine periodic checks.
Available at your facility or at our Vatva lab — same quality, more flexibility.
— AREAS WE SERVICE —
Bulk multimeter calibration with 1-day turnaround. Gujarat-wide courier service.
Why Choose Prism
Since 2004, every NABL multimeter certificate from Prism has been accepted by ISO 9001, pharma, and all QMS audit bodies — no rejections.
