KERN 327-151 — 20 kg OIML Class F1 control weight, polished stainless steel
The KERN 327-151 is a knob-shaped, stackable 20 kg control weight designed for precise calibration tasks in laboratories and industrial workshops
- OIML class F1 accuracy
- 20 kg nominal mass
- Polished stainless steel finish
- Stackable, knob-shaped design
Consistent compliance and traceable accuracy for measurement assurance
This calibration weight is specified as OIML Class F1, with a tolerance of 100 mg, which ensures repeatable results when verifying and adjusting balances. The classification indicates suitability for high-precision control tasks rather than legal-for-trade approvals; note that the EU first-type approval for weights will no longer be available after 30.11.2025. For sustained traceability and broad applicability, a DAkkS calibration is recommended, providing documented conformity to national and international calibration standards and helping to maintain measurement integrity across production and quality-control processes.
Robust finish and ergonomic handling to protect investment
Manufactured from polished stainless steel, the control weight resists corrosion and abrasion in workshop environments, reducing surface wear that could affect mass over time. The knob-shaped design simplifies placement and removal from balances, while the stackable form minimises storage footprint and secures orderly handling during multi-weight procedures. These design choices reduce handling errors and limit the need for frequent recalibration, supporting operational continuity.
Practical applications that improve workflow efficiency
Suitable for laboratories, calibration labs and industrial workshops, this 20 kg control weight supports routine verification of floor scales, bench balances and comparator set-ups. Using a high-precision reference reduces measurement uncertainty during part inspection or batching operations, which in turn limits production rework and downtime. The combination of certified accuracy and durable construction provides a cost-effective means to maintain process control and to document measurement reliability for audits and quality management.
Recommended storage and calibration approach to extend service life
To protect the reference surface and maintain accuracy, an appropriate carrying or storage case is advisable; accessories are available in the related section. Regular calibration—preferably with a DAkkS certificate—ensures the nominal mass remains within specified limits and supports traceability. Given the product’s classification and polished finish, correct storage and handling are key to preserving the reference condition and ensuring long-term performance.

Zubehör
Secure storage and reliable handling for a single F1 control weight, achieved through a padded wooden construction and compact design; ideal for calibration tasks where protection and clear classification matter. Order the wooden case directly via Metav Werkzeuge or consult our specialists for precise integration advice. KERN 337-151-100 Wooden Case – padded wooden case for a single 20 kg F1 control weight A KERN 337-151-100 wooden case designed for secure storage and transport of a single calibration/control weight up to 20 kg, combining durable construction with protective padding for workshop and laboratory use Padded interior for safe handling Designed for single 20 kg control weight Made from solid wood construction Compatible with F1 standard weights Protected storage that reduces handling risk The wooden case offers a padded interior that cushions a single 20 kg control weight during transport and storage, reducing the likelihood of nicks or surface damage that can affect measurement accuracy. Built from wood, the case provides stable support without introducing abrasive contact points; the compact design also keeps handling straightforward while the overall mass of the case is approximately 4 kg, making movement within the workshop manageable. This protective approach supports longer-term reliability of calibration artefacts and minimises the need for premature rework of reference weights. Designed to meet metrology class requirements Supplied for use with weights in the F1 to M1 range, the case is tailored to the demands of precision verification and calibration workflows. The F1 classification indicates suitability for high-accuracy reference tasks where dimensional and mass stability matter; storing a control weight in a dedicated, cushioned enclosure helps maintain the integrity required for traceable measurements. The clear classification and snug fit reduce accidental handling and contamination, which in turn keeps calibration intervals on schedule and supports consistent measurement results. Practical integration into calibration routines Labels such as the SKU and GTIN make inventory management straightforward, while the simple, robust construction ensures the case fits easily into existing storage systems and transport boxes. The wooden shell and internal padding are chosen for practical workshop use: the exterior withstands routine movement and the interior protects the weight’s surfaces. For teams consolidating suppliers, the case complements a broader metrology supply chain by providing a straightforward solution for single-weight safekeeping without unnecessary complexity.
