KERN 304-04 Weight Set — OIML class E1, 1 g–200 g, polished stainless steel

The KERN 304-04 is a precision OIML class E1 weight set designed for calibration and verification of analytical balances and precision scales in laboratories and quality control environments.

• OIML class E1 accuracy
• Nominal values 1 g–200 g
• Polished stainless steel knobs
• Supplied in a solid wooden case

Laboratory-grade accuracy for certified calibration

The set offers OIML class E1 performance, providing the low uncertainty required for verification of analytical and precision balances. Class E1 indicates the highest legal metrological standard for reference weights used in calibration labs, which supports reliable traceability to national measurement institutes. The tight tolerances reduce measurement uncertainty during routine checks and instrument validation, simplifying compliance documentation and enhancing confidence in test results.

Robust material and ergonomic design for frequent handling

Constructed from polished stainless steel, each weight resists corrosion and surface degradation, which preserves mass stability over time. The knob-shaped design ensures secure, repeatable handling with tweezers or gloves, lowering the risk of contamination or damage during transfers. Storage in a finely fitted wooden case protects the set from dust and mechanical shock, keeping calibration artefacts organised and immediately available for scheduled verification tasks.

Practical benefits for metrology and quality control workflows

Ideal for calibration laboratories, instrument service centres and production quality teams, this weight set streamlines verification procedures and minimises downtime during instrument checks. The combination of high-class accuracy and protective casing supports predictable maintenance intervals and efficient inventory management. Manufactured by KERN and supplied with identifiable product data, the set integrates into existing calibration regimes and supports clear documentation for audits.
