KERN 303-056 weight set — OIML E1, 1 mg–500 g, polished stainless steel
The KERN 303-056 is a precision OIML E1 weight set designed for laboratory calibration, reference weighing and verification tasks in metrology and quality control environments.
- OIML class E1 certified
- Nominal range 1 mg–500 g
- Polished stainless steel weights
- Supplied in aluminium case
Highest confidence for calibration labs and accredited testing
The OIML E1 classification signals the top tier of legal-metrology tolerance for reference masses. This set provides a verified basis for calibration chains, enabling traceable adjustments of analytical balances and mass comparators. By choosing an E1-class set, laboratories gain measurable assurance that reference procedures meet stringent regulatory expectations and that measurement uncertainty is minimised.
Safer handling and organised storage for fragile milligram weights
Knob-shaped designs and a polished finish improve tactile control when placing or removing individual masses, reducing handling error. Milligram weights within the set are stored separately in a protective plastic insert, while the complete set is carried in a robust aluminium case that shields components from dust and mechanical impact. These design features together lower the risk of contamination and deformation, extending service life and preserving metrological integrity.
Broad range covering routine reference to fine calibration
With a nominal span of 1 mg–500 g, the set covers both ultra-fine mass standards and common reference weights used across laboratories and production QA stations. This consolidated range helps to reduce the number of separate sets required for different tasks, simplifying inventory and ensuring that traceable standards are available for a wide variety of balances and comparators.
Built for longevity and repeatable performance
Constructed from polished stainless steel and manufactured to exacting standards, the set offers corrosion resistance and dimensional stability under normal laboratory conditions. The combination of high-quality materials and precise production supports consistent measurement results over prolonged use, helping facilities maintain compliance without frequent premature replacements.

FAQ
What does OIML E1 mean for a laboratory standard?
OIML E1 denotes the highest legal-metrology tolerance for reference masses; the KERN 303-056 set meets these limits and is suitable for use as primary reference weights in accredited environments.
Are the milligram weights protected during transport?
Yes, the milligram masses in the KERN 303-056 are placed in a separate plastic insert and the full set is supplied in an aluminium case to protect against impact and contamination.
Can the set be used for routine balance verification?
The 1 mg–500 g range of the KERN 303-056 makes it practical for both fine calibration of analytical balances and routine verification tasks across a variety of instruments.
What advantages does polished stainless steel provide?
Polished stainless steel offers dimensional stability and strong resistance to corrosion and surface contamination, which helps preserve mass values and reduces cleaning-related wear.
Is the set suitable for establishing traceability chains?
Yes, the E1 classification and manufacturing quality of the KERN 303-056 support traceable calibration chains when combined with documented calibration certificates.

Zubehör
Take advantage of the combination of robust aluminium protection, precise compatibility with calibration classes and a lightweight, compact design to keep standard weight sets organised and safe. Order the case directly via Metav Werkzeuge or ask our consultants for tailored advice. Aluminium-protected Case KERN 313-050-600 — protective case for standard weight sets, 1 mg–500 g The Aluminium-protected Case is a lightweight, rigid transport and storage solution designed for standard calibration weight sets in laboratory and workshop environments. Aluminium-protected construction Suitable for 1 mg–500 g weight sets Compatible with classes E1–M1 Knob/compact format for efficient storage Built for reliable calibration workflows and secure transport The case’s aluminium-protected outer shell delivers mechanical resilience without excessive mass, providing secure transport for sensitive calibration masses. Designed for 1 mg–500 g weight sets and compatible with E1–M1 accuracy classes, the etui secures individual pieces in a knob/compact layout that minimises movement during handling. This reduces the risk of damage and the need for recalibration, supporting continuous, predictable operation in metrology chains. Organised layout that speeds up daily routines A compact internal arrangement keeps weights separated and accessible, enabling faster selection and return to storage during quality control cycles. The knob/compact configuration simplifies identification and handling of small masses while preserving their surfaces and tolerances. For workshops and laboratories that prioritise efficiency, the structured interior contributes to a smoother workflow and fewer interruptions for searches or cleaning. Robust protection without compromising portability With a total mass of approximately 0.7 kg, the case balances robust protection with easy handling. The aluminium construction shields contents from external mechanical impacts and environmental strain during transport. The rigid shell also serves as a practical protective barrier in shared storage areas, reducing the likelihood of accidental knocks affecting highly accurate weight sets. Suitable for standardised metrology environments Intended for standard weight sets in the knob/compact form and for use with E1–M1 classes, the case supports conformity and traceability requirements common in calibration labs and regulated production environments. The design focuses on preserving the geometric and surface integrity of masses used for calibration, contributing to reliable measurement chains and fewer unplanned calibrations.
