— WHAT IS MASS, VOLUME & FLOW CALIBRATION —
Think of it like a shopkeeper's weighing scale. If the scale shows 1 kg but the real weight is 1.05 kg, the shopkeeper is cheating customers without knowing it. The same happens in labs and factories — if a pipette dispenses 95 µL instead of 100 µL, or a weighing balance reads 50g low, every formula, batch, or product is wrong.
Mass, volume, and flow calibration means checking your balance, weight, pipette, or flow meter against a certified reference, fixing any error, and issuing an NABL certificate as proof — required by FDA, ISO 9001, Legal Metrology, and GMP auditors.
Product Safety
Wrong dosing due to an un-calibrated pipette or balance can cause under/over-dose in pharma or food products.
Quality Control
Precise mass and volume measurements ensure every batch meets the specification and passes QC testing.
Legal Compliance
Legal Metrology Act and FDA/GMP require calibrated weighing and volumetric instruments with valid certificates.
Cost Saving
Catching balance drift or pipette error early prevents batch failures, raw material waste, and audit penalties.

— OUR PROCESS —
Every calibration follows our documented ISO/IEC 17025 procedure — traceable, repeatable, auditable.
Instrument received, tagged with job number. Type, capacity, range, make, model noted. Pre-calibration condition documented.
Instrument measured at defined points against NPL/OIML-traceable references. As-found readings at zero, mid, and full scale documented.
Readings compared to traceable reference weights, certified flow rigs, or gravimetric standards. Error calculated at each calibration point.
Span, zero, and linearity adjustments made where applicable. Smart flow transmitters adjusted. Correction tables issued if required.
Post-adjustment readings verified at all points. Expanded measurement uncertainty calculated per ISO/IEC 17025. Pass/fail recorded.
NABL CC-2480 certificate with as-found/as-left data, expanded uncertainty, OIML/NPL traceability, and digital delivery within 24 hours.

— NON-NABL CALIBRATION —
For routine maintenance or bulk calibration not requiring NABL certification, Prism provides cost-effective non-NABL mass and flow calibration with the same trained engineers and traceable reference standards.
All calibrations use OIML/NPL/BIPM-traceable reference standards regardless of NABL or non-NABL certificate type.
Non-NABL mass/flow jobs completed faster — ideal for urgent maintenance or bulk batch calibration.
Non-NABL calibration priced lower — right choice for internal checks and non-audit use cases.
Available at our Ahmedabad lab and as onsite service across Gujarat — with or without NABL.
