KERN 303-04 weight set — OIML Class E1, 1 mg–200 g, polished stainless steel

KERN 303-04 weight set is a laboratory calibration set designed for high-precision verification of analytical and precision balances, supplied in a protective wooden case with separate storage for milligram weights

• OIML Class E1 accuracy
• Range 1 mg–200 g
• Polished stainless steel weights
• Separate plastic case for milligram weights

Laboratory-grade accuracy for repeatable results

The OIML Class E1 classification guarantees the set meets the highest international requirements for calibration weights used in laboratories and calibration houses. With a nominal span of 1 mg–200 g, the set reduces measurement uncertainty across analytical and microbalance ranges, enabling precise verification of instruments where even minimal deviations matter. Using such a certified classification supports consistent measurement procedures and contributes to reliable documentation and quality assurance in regulated environments.

Durable materials and secure storage to protect measurement integrity

Manufactured from polished stainless steel and formed in a button shape, the weights resist surface degradation and are easy to handle without risking contamination. The presentation wooden case provides secure transport and organised storage, while the smallest milligram increments are housed in a separate plastic case, preventing damage and simplifying access during delicate work. These design choices minimise handling errors and extend service life, making routine use and periodic checks straightforward for laboratory technicians.

Practical completeness that streamlines calibration workflows

A single set covering 1 mg–200 g reduces the need to source multiple individual weights, simplifying inventory and accelerating calibration tasks. The combination of high-accuracy classification and robust construction means fewer replacements and less downtime for instruments, which supports efficient operational planning. For procurement, the lightweight, compact set offers clear logistic advantages while maintaining the traceable quality required for internal quality systems and external audits.
