— WHAT IS WEIGHING BALANCE CALIBRATION —
Think of a quality lab that relies on a weighing balance 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.
Weighing Balance 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.
— INSTRUMENTS COVERED —
Analytical / Semi-Micro / Precision / Bench / Platform / Floor Scale · All Makes · OIML R 76 · NABL
High-precision analytical balances with 0.1 mg or 0.01 mg readability.
Precision balances with 1 mg to 1 g readability for general laboratory use.
Semi-micro balances with 0.01 mg readability and 100 g capacity.
Macro analytical balances with higher capacity and 0.1 mg readability.
Industrial electronic balances for warehouse, production, and quality control.
Moisture analyzer balances for measuring moisture content by halogen drying.
— OUR PROCESS —
Balance received and allowed to stabilise at lab temperature (20 ± 2°C) for at least 30 minutes before calibration.
Balance levelled using built-in bubble level. Zero (tare) repeatability checked. Sensitivity test with minimum detectable mass performed.
Calibrated at 5 mass setpoints: 10%, 25%, 50%, 75%, 100% of nominal capacity using OIML F1/F2/M1 class reference weights. Error and repeatability documented.
Repeatability: same mass loaded 5 times. Eccentricity: mass placed at 5 positions on the pan. Standard deviation and maximum eccentric error reported.
Maximum error, mean error, standard deviation, and expanded uncertainty (k=2) per GUM. Compared to OIML accuracy class or manufacturer specification.
NABL CC-2480 certificate with mass calibration data, repeatability, eccentricity, uncertainty (k=2), OIML R 76 / OIML R 111 traceability.

Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Weighing balance certificates accepted by pharma GMP (21 CFR Part 211), ISO 9001, IATF 16949, and all process 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 —
On-site or laboratory calibration. 1-day turnaround for most balances.
Why Choose Prism
Since 2004, every NABL balance certificate from Prism has been accepted by pharma GMP, ISO 9001, and IATF 16949 auditors — no rejections.
