KERN 303-084 weight set — OIML E1, 1 mg–5 kg, polished stainless steel, plastic case
A KERN 303-084 precision weight set designed for laboratory and calibration use, covering nominal values from 1 mg to 5 kg for balance verification and routine accuracy checks.
- OIML class E1 accuracy
- Range 1 mg–5 kg for full-scale calibration
- Polished stainless-steel construction
- Milligram weights in separate plastic insert
- Secure plastic case for transport and storage
Laboratory-grade accuracy for critical measurements
The set is specified to OIML E1, the highest class for calibration weights intended for the most demanding verification tasks. That classification defines the permissible tolerance and ensures repeatable performance when checking analytical and precision balances. With a nominal range of 1 mg–5 kg, the set covers both microgram-scale and kilogram-scale calibrations, reducing the need for multiple individual purchases and streamlining traceability chains. This translates into fewer calibration steps and a lower risk of measurement-related production delays.
Robust materials and handling that preserve results
Manufactured from polished stainless steel, the weights resist corrosion and surface wear that could degrade mass values over time. The button shape minimises surface contact and eases handling with forceps, reducing contamination and handling errors during routine use. Milligram weights are stored separately in a dedicated plastic insert, which keeps the smallest pieces protected and organised. The complete set is supplied in a plastic case designed for safe transport and storage, helping to maintain the condition required for long-term accuracy.
Practical organisation and quality-system benefits
A well-structured weight set supports efficient calibration workflows and documentation. The separate compartment for milligram weights and the clearly graduated nominal values simplify inventory control and help meet internal quality-management requirements. Using a high-class calibration set lowers uncertainty margins when checking balances, which benefits both process control and compliance during audits. For workshops and laboratories aiming to reduce measurement deviations, this set offers a direct route to more consistent results and fewer corrective actions.

FAQ
What does OIML class E1 mean for accuracy and use?
OIML class E1 denotes the tightest tolerances for calibration weights; the KERN 303-084 set meets these requirements and is suitable for the most demanding laboratory and verification tasks.
Can the set be used to calibrate analytical balances and larger scales?
Yes — the nominal range from 1 mg–5 kg enables verification of both analytical balances and larger precision scales, reducing the need for multiple weight sets.
How should the weights be handled and stored to maintain accuracy?
Handle the weights with forceps or gloves to avoid contamination; store them in the supplied plastic case and the separate insert for milligram weights to preserve surface integrity and long-term accuracy.
Is the material resistant to corrosion in workshop environments?
The polished stainless-steel construction offers strong resistance to corrosion and wear, supporting longevity when properly maintained.
Are the smallest weights organised to prevent loss or damage?
Yes — milligram weights are supplied in a dedicated plastic insert within the case, providing protection and clear organisation for routine use.

Zubehör
Take advantage of secure, lightweight storage that protects standard weight sets up to 5 kg, compatible with calibration classes E1–M3, and designed specifically for button and compact formats; order via Metav Werkzeuge or consult our specialists for guidance. KERN 313-082-400 Plastic Case — for standard weight sets up to 5 kg, E1–M3 A KERN 313-082-400 Plastic Case engineered to protect and organise standard weight sets (button/compact form) for calibration, laboratory and workshop use Plastic case for weight sets up to 5 kg Compatible with calibration classes E1–M3 Designed for button and compact weights Lightweight construction; easy transport Faster calibration workflows with protected storage The robust plastic case provides protected, organised storage for standard weight sets, supporting nominal values from 1 mg–5 kg and calibration classes E1–M3. By keeping weights secure and clearly arranged, routine checks and calibrations require less preparation time and handling, which increases throughput in busy calibration labs and testing environments. The case’s structured capacity reduces the risk of contamination and mechanical damage, helping maintain traceability and measurement reliability. Tailored layout for compact and button weights Designed for the specific format of button and compact weights, the internal layout is optimised to hold standard pieces securely during transport and storage. The solution is explicitly not suitable for cast weights, ensuring customers select the correct storage for precision masses rather than heavy, cast components. Clear compatibility with compact designs supports orderly handling and faster identification of required nominal values during set-up and inspections. Lightweight, durable design for easy handling With a total mass of approximately 1.5 kg, the case balances protection with portability: it is light enough for frequent movement between benches or labs yet durable enough to withstand day-to-day operational stress. The plastic construction offers resistance to moisture and common workshop contaminants, contributing to long service life and fewer replacements. Reduced handling weight also lessens manual strain and simplifies logistics for mobile calibration tasks. Compliance support and workshop efficiency Built to fit recognised weight class standards, this case assists in maintaining compliant storage for precision masses and supports efficient inventory management in industrial metrology. The German origin reinforces expectations for consistent manufacturing quality. When combined with a reliable ordering partner, this storage solution helps centralise supplies and reduces procurement complexity for calibration houses and workshops.
