Mass (Industrial or Precision) Calibration
Weighing Up Accuracy: Expert Mass Calibration Services
All our weight references are calibrated and traceable to the SI unit of mass, aligning with global standards for metrological traceability. Regular re-calibrations of our standards further uphold accuracy and maintain the traceability of our calibration services.
In addition to offering endorsed calibration, NWI Calibration has both inhouse and onsite capabilities for mass calibration. With ISO/IEC 17025 aka NATA endorsement, regulation 13 endorsement and trade verification for masses for both inhouse and onsite for industrial masses, and in 4 of our laboratories for precision masses.

Mass and Precision Weights Calibration Scope
Our calibration scope covers a variety of equipment for Masses and Reference Weights including:



Why Choose NWI Calibration for your Mass Calibration?
Precise and reliable weighing results depend on accurate mass calibration services. When it comes to balances, it is crucial to have confidence in the reference weights used for calibration. At our NATA-accredited calibration laboratories, we specialise in calibrating and adjusting weights to ensure optimal accuracy. Our meticulous calibration procedures are backed by NATA-endorsed calibration, detailed documentation, and a comprehensive calibration certificate.
Our Mass Calibration Services go beyond simply calibrating weights. NWI Calibration adheres to the strict requirements outlined in ISO/IEC 17025, ensuring precise Regulation 13 verification and trade verification where required. This includes reporting conventional mass, expanded uncertainty, and traceability. Our calibration certificate serves as a tangible record of the calibration process, allowing you to demonstrate compliance with industry standards and regulatory requirements.
NATA Accreditation
NWI Group’s NATA-accredited mass calibration services ensure precision and compliance for a wide range of mass standards and industrial mass standards. Our advanced calibration laboratory operates with exceptional Calibration and Measurement Capability (CMC), delivering highly accurate measurements across various weight ranges.
With a calibration uncertainty as low as 5 μg for for Mass Standards as small as 1 mg, and from 5 mg for Industrial mass standards as small as 100 g and extending up to larger masses up to 1000 kg, our expertise guarantees traceability to national and international standards.
