KERN 303-054 weight set (OIML E1) — 1 mg–500 g, polished stainless steel

The KERN 303-054 is a precision weight set designed for verification and routine checks of high-resolution balances in laboratories and calibration workshops.

  • OIML E1 accuracy for laboratory verification
  • Range 1 mg–500 g in polished stainless steel
  • Button form weights with fine tolerances
  • Separate plastic case for milligram weights

Ensure measurement confidence with laboratory-class accuracy

The set delivers OIML E1 conformity for demanding verification tasks, covering the nominal range 1 mg–500 g to match the needs of high-resolution balances. This classification indicates the highest level of international accuracy available for test weights, reducing measurement uncertainty when verifying analytical and microbalances. By selecting an instrument classified for such fine tolerances, measurement processes can meet stringent quality requirements and support documented verification routines in controlled environments.

Robust materials reduce handling risks and long-term drift

Manufactured from polished stainless steel, the components combine corrosion resistance with a surface finish that minimises contamination and handling marks. The button form design facilitates secure contact with forceps and reduces the risk of tipping or misplacement during exchange, which aids repeatability. These material and shape choices contribute to mechanical stability, making the set suitable for frequent laboratory use where consistent performance and longevity are required.

Organised storage protects the smallest weights and supports workflow

All weights are supplied in a compact plastic case with the milligram weights held in a separate internal pocket for improved protection and organisation. This arrangement keeps delicate items isolated, simplifies inventory checks and shortens time spent searching for the correct nominal value during verification procedures. Originating from Germany, the set reflects conservative manufacturing controls and a quality-oriented supply chain, which supports traceable procurement and reproducible handling within calibration processes.

FAQ

What does OIML E1 mean for verification tasks?
OIML E1 designates the highest international class for test weights; the KERN 303-054 set meets these limits and is intended for verification of analytical and microbalances where minimal uncertainty is required.

Can the set be used for routine laboratory checks?
Yes, the KERN 303-054 weight set is designed for regular verification cycles and organised storage helps maintain condition between uses.

How are the smallest weights protected during transport?
The milligram weights within the KERN 303-054 are held in a separate internal plastic case, preventing contact with larger weights and reducing wear.

Is the material suitable for long-term laboratory use?
The polished stainless steel construction of this weight set provides corrosion resistance and a finish that is easy to clean, supporting durable application in laboratory environments.

Does the set support traceable verification procedures?
The classification and construction of the KERN 303-054 support standardised verification workflows and procurement records consistent with traceability practices.

500g Plastic Case For Standard Weight Sets, For Classes E1–M3, Compact Button Design - KERN

Take advantage of durable, lightweight storage and organised inserts to keep calibration weights safe and accessible; the compact design supports routine handling and workshop transport. Order the plastic case directly via Metav Werkzeuge or ask our consultants if needed. Plastic case KERN 313-052-400 – Carrying case for standard calibration weight sets, up to 500 g The Plastic case KERN 313-052-400 is a compact carrying solution for standard calibration weight sets, providing organised storage and protection for weights used in precision metrology. Plastic case for standard weight sets up to 500 g Designed for weight classes E1 to M3 Compact, lightweight design for workshop transport Compatible with button/compact weight formats Secure storage that preserves calibration accuracy The robust plastic construction provides a protective outer shell that shields calibration weights from dust, knocks and moisture during storage and transit. Inside, the layout is tailored for standard subdivision sets so that each mass is held securely; this reduces the risk of surface damage and contamination that can affect measurement results. Conserving the surface integrity of calibration masses supports repeatable weighing and helps maintain traceability between calibration intervals. Organised layout for efficient handling and traceability A clearly arranged internal layout enables quick identification and removal of individual masses, which speeds up routine checks and decreases handling time. The case is specified for weight classes E1–M3 and nominal values up to 500 g, matching common calibration procedures in laboratories and workshops. By keeping sets together in a dedicated container, record-keeping and procedural compliance are simplified, which supports quality systems and audit readiness. Workshop-ready: portable, lightweight and practical With a low own weight of 0.35 kg, the case is easy to carry between bench, calibration station and storage shelf. The compact format reduces occupied space on the workbench and is convenient for mobile service technicians who require a reliable transport solution. The material resists routine workshop wear and can be wiped clean, so maintenance is straightforward and no specialist care is required to keep the case operational. Clear scope of use and compatibility guidance The design caters specifically to button/compact mass formats and standard weight sets; it is not suitable for cast weights or atypical mass geometries. This distinction matters because cast masses often require bespoke recesses or heavier-duty containment. If there is uncertainty about compatibility with a particular set, the case’s intended scope—standard subdivision, E1 to M3, up to 500 g—should be checked before purchase to ensure correct fit and continued measurement reliability.

The case is specified for nominal values up to 500 g; weights above this range are not covered by the internal layout and may not be held securely. Can the case be used for different weight classes? Yes, the container is designed for weight classes E1 to M3, supporting the common precision classes used in calibration laboratories. Does the case protect weights during transport? The plastic shell and organised recesses provide protection against shocks and contamination during routine transport and handling. Are cast weights suitable for storage in this case? No, the case is not suitable for cast weights; those typically require specific accommodation due to different shapes and higher mass. Who supplies this product and where is it shipped from? The product is supplied by KERN and can be ordered via Metav Werkzeuge; stock is distributed from Emmerich for delivery across Europe. KERN, Germany — Contact: not provided
