Ensure weighing accuracy with certified calibration weights
Calibration weights are precision mass artefacts used to verify, adjust and document scale performance, providing process security and repeatable results in production, quality assurance and laboratories. They come in defined nominal values and accuracy classes such as E1, F1 and M1, so you can match the right weight to the scale’s readability and application to avoid false confidence or unnecessary cost. Correct handling—using gloves or tweezers, storing weights in their case and avoiding contamination—keeps them reliable, while routine checks at multiple points in the weighing range reveal issues caused by vibration or temperature changes.

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.

Ensure measurement reliability with certified test weights
Test weights are defined mass artefacts used to verify, adjust and document the performance of scales across production, laboratory and quality assurance environments. They provide the objective reference needed to confirm accuracy, repeatability and process reliability where documented results matter.
How test weights work and where they matter
Test weights serve as traceable references with fixed nominal values — for example 1 g, 100 g, 1 kg or 20 kg — and are manufactured to specific accuracy classes so that permitted deviations are known and comparable. In practice they are used to check a scale’s reading at one or several points within its range, to distinguish between calibration (checking and documenting deviation) and adjustment (setting the scale to read correctly). Typical situations include routine production checks, audit-prepared quality control, laboratory validation and fault-finding when instability, vibration or environmental factors affect readings.
Immediate performance gains for production and quality assurance
- increase measurement confidence by using weights matched to the application and scale resolution
- reduce downtime and troubleshooting time through systematic multi-point checks (lower, mid, upper range)
- protect process validity by choosing the correct accuracy class: E1, E2, F1, F2, M1, M2, M3
- limit handling-related error: use tweezers for small weights and clean gloves for larger items
- extend usable lifetime through disciplined storage in protective cases and regular control or recalibration

FAQ
What exactly are test weights?
Test weights are defined mass artefacts with fixed nominal values that are used to check, adjust or document scale performance within quality assurance and calibration workflows.
Which accuracy classes are available and when should I use them?
Accuracy classes range from E1/E2 for the highest demands, through F1/F2 for precise everyday applications, to M1–M3 for robust industrial or platform scales. Select the class that matches the required measurement uncertainty and the operating environment.
How often should I check my scale with test weights?
Frequency depends on the criticality of the process: critical operations often require daily or per-shift checks, while less critical applications may use weekly or monthly intervals; always check after location changes or suspect readings.
Why must test weights not be touched with bare hands?
Skin oils and moisture alter surface mass and can introduce measurable errors, especially for small nominal values. Use tweezers or clean gloves to maintain traceability and reliability.
What is the practical difference between calibration and adjustment when using test weights?
Calibration documents how far a scale deviates from the nominal value; adjustment actively corrects the scale to bring it back into tolerance. Both processes make use of test weights but serve different quality objectives.
Metav and KERN & Sohn provide the products, documentation and calibration pathways to integrate test weights into routine quality assurance — ensuring your measurements remain verifiable, repeatable and audit-ready.
