Calibration weight set KERN 304-08 — OIML Class E1, 1 g–5 kg

The Calibration weight set KERN 304-08 is a laboratory‑grade verification set intended for high‑precision balance calibration and routine metrological checks in workshops and calibration labs.

• OIML Class E1 precision
• Range 1 g to 5 kg
• Polished stainless-steel, knob style
• Supplied in wooden storage case

Laboratory-grade accuracy for traceable verification

The set delivers OIML Class E1 accuracy, the benchmark for calibration laboratories that require minimal uncertainty and repeatable results. Class E1 weights are manufactured and finished to very tight tolerances, which reduces measurement uncertainty during verification and adjustment cycles. Using a high‑accuracy verification set helps maintain process control on precision balances, shortens adjustment intervals and supports documented quality systems such as ISO 9001 by improving the reliability of mass measurements.

Robust materials and ergonomic handling for daily use

Constructed from polished stainless steel, the individual button‑style weights offer excellent corrosion resistance and a smooth, easy‑to‑clean surface that preserves nominal mass under normal laboratory conditions. The knob‑shaped design simplifies handling while reducing the risk of contamination or finger marks that could affect small masses. Supplied in a fitted wooden case, the set remains organised and protected, allowing fast access during routine checks and safe transport between stations.

Designed to integrate with calibration workflows

The set covers the practical span from 1 g–5 kg, enabling verification of a wide range of balances without multiple kits. Clear identification with SKU and GTIN facilitates inventory control and traceability in calibration records. Inclusion in a documented verification routine supports measurement assurance and helps to detect drift early, reducing downtime and the risk of out‑of‑tolerance production. The high manufacturing standard of the set provides a solid basis for internal audits and external accreditation assessments.
