KERN 347-056 Hook Calibration Weight — 20 g, OIML M1, Stainless Steel
KERN 347-056 is a hook calibration weight designed for routine balance and scale checks in workshops and laboratories, offering OIML M1 class accuracy in a compact suspension format.
- OIML M1 class accuracy
- Fine-turned stainless steel finish
- Nominal mass 20 g for precise checks
- Hook suspension for direct weighing
Consistent accuracy for routine calibrations
The OIML M1 classification and a specified tolerance of 2.5 mg make this weight a dependable choice for recurring verification tasks. As a single calibration weight, it reduces uncertainty when checking small-capacity scales and analytical balances: the defined tolerance gives a clear quantitative basis for pass/fail decisions during daily or shift-based checks. The compact 20 g nominal mass and low mass drift support predictable instrument behaviour, allowing quality managers to plan maintenance intervals with confidence.
Robust finish that stands up to daily handling
Manufactured from fine-turned stainless steel, the weight resists corrosion and surface damage from repeated handling and routine cleaning. The turned surface not only provides a clean aesthetic but also reduces contamination risks and wear on the suspension point. For users who value longevity and low-maintenance equipment, this finish minimises the need for replacements and preserves measurement stability over time, which is especially important in production environments where frequent checks are required.
Practical suspension design for fast checks
The hook configuration enables direct suspension from scale pans or fixtures, speeding up in-situ verification and reducing handling steps compared with clamped or box-mounted weights. This design simplifies workflows when performing comparative checks across multiple instruments, helping to streamline calibration protocols. As a single, purpose-built hook weight, it integrates easily into existing test procedures and supports efficient traceable checking without additional adapters.

Take advantage of the combination of secure storage, compact handling and class‑compliant organisation to protect calibration weights and simplify workflow; order the case directly via Metav Werkzeuge or consult our advisors for specification support. KERN Plastic Case for Single Weights 347-050-400 — for 10 g–20 g weights, classes F1–M3 The KERN Plastic Case for Single Weights 347-050-400 offers organised, transport‑ready storage for single calibration weights used in workshops and laboratories. Plastic case for single calibration weights Fits button/compact weight designs Compatible with weight classes F1 to M3 Protect measurement integrity with compact, secure storage The KERN Plastic Case is engineered to safeguard single calibration weights during storage and light transport. The plastic construction combines low weight with dimensional stability, reducing the risk of accidental scratches or contamination that can affect mass values. By keeping individual weights in a dedicated compartment, the case helps maintain measurement accuracy and continuity in calibration routines, supporting efficient quality control and repeatable weighing processes. Lightweight organisation that saves space and handling time A slim, lightweight enclosure simplifies handling on the workbench and in the calibration lab. At approximately 0.02 kg, the case adds negligible mass while offering clear separation for button/compact weight geometries, which minimises handling time and reduces the chance of cross‑contamination between masses. The compact design aids storage density and enables quicker inventory checks, contributing to streamlined workflow and consistent measurement results. Clear compatibility with calibration classes and nominal values Designed for nominal values in the 10 g–20 g range and certified weight classes F1–M3, the case supports commonly used small reference weights in laboratories and service centres. The case accommodates the typical form factors of single weights, ensuring that calibration artefacts remain correctly seated and identifiable. For users less familiar with class designations: F1–M3 indicate graded tolerances; choosing a case that matches those classes helps preserve the reference condition required for traceable weighing procedures.
