KERN 307-16 calibration weight — OIML Class E1, 50 kg, polished stainless steel
The KERN 307-16 is a knob-shaped calibration weight designed for laboratory and industrial scale verification where repeatable, certified mass values are required
- OIML class E1 for highest accuracy
- 50 kg nominal mass, precision 25 mg
- Polished stainless steel, knob design
Laboratory-grade accuracy that reduces calibration uncertainty
The OIML Class E1 designation indicates the weight meets the strictest international tolerances for reference masses, suitable for primary checks and accredited verification routines. With a nominal mass of 50 kg and a declared tolerance of 25 mg, this reference mass supports traceable adjustments and uncertainty budgets in high-precision metrology. The specification minimises rework and reduces the frequency of repeat measurements, which contributes directly to production efficiency and audit readiness.
Robust design for safe handling and long-term stability
Manufactured from polished stainless steel, the weight combines corrosion resistance with a finish that eases routine cleaning and prevents contamination of delicate balance pans. The knob shape provides a secure grip for controlled placement and removal, lowering the risk of handling error and surface damage. These design choices extend service life and preserve calibration integrity, so verification intervals can be planned with confidence rather than constant corrective work.
Seamless integration into quality systems and calibration workflows
This reference mass is prepared for immediate use in laboratory and industrial environments, supporting documented calibration procedures and ISO-compliant traceability chains. The robust material and exacting tolerance simplify the establishment of measurement uncertainty and support accredited processes. For transport and storage, a protective case is recommended because the high-accuracy class benefits from minimal handling and stable environmental conditions; Metav Werkzeuge offers suitable accessories to complete a reliable calibration routine.
Choose the KERN 307-16 for uncompromised reference accuracy and contact Metav Werkzeuge in Emmerich for accessory recommendations and secure, reliable supply from our central quality filter.

FAQ
What does OIML Class E1 mean for measurement tasks?
OIML Class E1 denotes the highest international tolerance class for reference masses; the KERN 307-16 meets these limits and is therefore suitable for primary verification and calibration where minimal uncertainty is required.
Is a protective case necessary for this weight?
Yes — due to the very fine tolerance, a protective case is strongly recommended to avoid contamination and mechanical damage; Metav Werkzeuge lists suitable etuis in the accessories section.
What is the declared accuracy of the 50 kg weight?
The KERN 307-16 has a nominal mass of 50 kg with a declared tolerance of 25 mg, enabling tight uncertainty control in calibration procedures.
Can this weight be used in accredited calibration laboratories?
The combination of OIML Class E1 specification and polished stainless construction makes this reference mass appropriate for use in accredited routines and documentation that require traceable reference standards.
