Reliable reference for precision workflows
A certified reference mass in OIML E1 provides the tightest legal-class accuracy suitable for calibration laboratories and high-end industrial verification. With a 5 kg nominal value and an OIML tolerance of 2.5 mg, this single weight reduces measurement uncertainty and supports repeatable results during routine checks. The high-precision classification helps streamline calibration procedures and reduces downtime by cutting the number of re-measures needed to confirm instrument performance. Where documented traceability and conformity are part of quality management, this mass standard supports uncomplicated integration into existing calibration chains.
Built for regular use and careful handling
The mass is manufactured from polished stainless steel, giving good resistance to surface corrosion while presenting a smooth finish that minimises particulate adherence. Its button form concentrates mass centrally for stable placement on pans and helps with handling during frequent transfers. Cylinder dimensions of 80×140 mm are balanced for laboratory balances and industrial scales. For such a high-accuracy artefact a protective case is recommended to prevent contamination and mechanical damage during storage and transport; Metav provides a selection of suitable cases to preserve long-term performance and calibration integrity.
Compliance, traceability and system benefits
This single weight is supplied by KERN and carries the necessary identifiers for documentation and audits, making it straightforward to include in quality systems and calibration protocols. Using a certified E1 mass assists laboratories in meeting accreditation requirements and supports a transparent calibration history. Supplied through Metav Werkzeuge’s quality-controlled logistics, the item benefits from careful stock handling at the Emmerich site, which acts as a quality filter for European customers and contributes to reliable delivery and documentation.
