KERN 356-88 — Calibration weight, OIML Class M2, 20 kg block
The KERN 356-88 is a 20 kg block calibration weight for verification and routine calibration of industrial and workshop scales, certified to OIML Class M2 for standardised accuracy.
- OIML Class M2 accuracy
- 20 kg block design for stability
- Coated cast iron for durable protection
Accurate measurement as the basis for reliable decisions
The primary benefit of an OIML-classified weight is measurement certainty. Certified as OIML Class M2, this block offers a declared tolerance 3 g, making it suitable for routine verification and adjustment of mid-range scales where standardised accuracy is required. The nominal mass of 20 kg provides a stable reference point for test routines, reducing the need for frequent repeat measurements and supporting consistent production quality. Explanation of terms is straightforward: OIML classes define permissible deviations, and Class M2 indicates suitability for general industrial and commercial control tasks.
Robust construction that reduces handling risks
Built as a block from coated cast iron, the design focuses on durability and occupational practicality. The compact block form minimises tipping and allows secure placement on scale pans, while the protective coating reduces surface wear and corrosion in workshop environments. These features translate into lower maintenance for the weight and fewer interruptions during calibration cycles. The solid construction also aids in handling ergonomics when transferring the weight between test stations, supporting faster and safer scale checks.
Supply reliability, traceability and professional backing
Choosing a verified calibration weight is part technical decision and part procurement assurance. Supplied by KERN and distributed via Metav Werkzeuge’s quality-controlled inventory in Emmerich, the item benefits from an established supply chain and documented traceability. Metav’s long-standing experience and centralised stock reduce lead times and provide a clear supply route for maintenance programmes. This combination of certified reference mass and dependable distribution supports audit readiness and fosters confidence in measurement results across production and inspection processes.

Take advantage of a robust combination of lightweight aluminium protection, a padded interior and certified suitability for calibration classes F1–M3 to keep block weights safe in transit and storage. Order the case directly via Metav Werkzeuge or consult the Metav team for specification support. KERN 346-080-600 Aluminium-protected case for block weights, padded The Aluminium-protected case 346-080-600 is a padded transport and storage solution designed for block calibration weights used in laboratory and industrial environments. Aluminium protection housing Padded interior for secure storage Designed for block weights up to 20 kg Suitable for weight classes F1–M3 Robust protection that preserves calibration integrity This lightweight aluminium housing combines structural rigidity with reduced mass, creating a reliable shell for sensitive calibration artefacts. The internal padding secures each block against shocks and vibrations, lowering the risk of dents or surface damage that could alter mass distribution and affect accuracy. For metrology departments and service technicians, a well-protected weight reduces the frequency of re-calibration and associated downtime. The transport case is engineered to match the handling patterns typical for laboratories and mobile calibration services, translating to measurable savings in time and maintenance costs. Designed for calibration workflows and secure handling The case is tailored for block weights, offering precise cut-outs and cushioned support to prevent movement during handling and transit. By ensuring that each weight remains immobile, the case helps maintain the declared tolerance class throughout storage and transport. Compatibility with F1–M3 tolerance classes indicates suitability for a broad range of calibration tasks, from precision laboratories to routine verification in production environments. The combination of a corrosion-resistant outer shell and internal padding also simplifies logistic processes: weights can be moved between sites without additional packaging and with preserved traceability. Practical meaning of classes and how they benefit operations Tolerance classes such as F1 and M3 specify permissible deviation ranges and are widely used in traceable mass measurement. Choosing a dedicated storage solution for weights intended for these classes safeguards the nominal value against mechanical or environmental damage that could invalidate the calibration status. For teams responsible for quality assurance, using a purpose-built protective case reduces the risk of non-conformances during audits and supports consistent measurement results. The case also supports efficient organisation in the workshop or lab, keeping block weights accessible, identifiable and ready for use.
