This comprehensive 5 kg calibration set is constituted with individual weights manufactured in full compliance with OIML R111-1 for Class E1, the highest classification for reference standards. The set provides a complete, traceable mass standard for the precise calibration and adjustment of high-resolution analytical and precision balances. Each weight within the set is essential for performing routine performance checks, linearity verifications, and full calibrations to ensure instruments are operating within their specified tolerances.
The weights are finished to a high polish, minimizing surface area and adsorption characteristics to maintain mass stability. The set is accompanied by an Accredited Certificate, providing documented proof of the individual weight values and their uncertainty, which is critical for maintaining ISO/IEC 17025 accreditation and audit trails. Supplied with a dedicated protective case and proper handling tools, this set is designed for long-term stability, safe transport, and correct usage to preserve its exacting specifications.
