KERN 304-03 — OIML E1 weight set, 1 g–100 g, polished stainless steel

The KERN 304-03 is a precision OIML class E1 weight set designed for the calibration of analytical and laboratory balances where highest accuracy and traceability are required.

• OIML class E1 accuracy
• 1 g–100 g range in button form
• Polished stainless steel weights
• Supplied in protective wooden case

Precise calibration standard for laboratory balances

This weight set provides a compact and reliable solution for routine and certification calibrations. As an OIML E1 mass standard, the set meets stringent tolerance limits and supports consistent measurement results, reducing the need for frequent rechecks. The polished stainless steel construction minimises surface contamination and eases cleaning, which helps maintain long-term accuracy. For users with limited metrology experience, OIML E1 denotes the highest class for small mass standards and is typically used where the balance resolution and performance demand traceable reference masses.

Robust design that protects instrument investment

The button-shaped weights are finished to a high polish and stored in a tailored wooden case, providing mechanical protection during transport and storage. The compact format conserves bench space while ensuring each mass sits securely in its recess to avoid damage or loss. Choosing a set with this combination of durable material and protective packaging reduces downtime for recalibration and protects the performance of sensitive balancing equipment, delivering a measurable efficiency gain for laboratory workflows.

Traceability and practical handling in everyday use

The complete set facilitates straightforward traceability and documentation for quality management systems without unnecessary complexity. The total set mass and individual weight denominations support stepwise checks of a balance’s linearity and repeatability. Careful handling is still recommended: use tweezers or gloves as appropriate to prevent contamination; occasional cleaning with a lint-free cloth preserves the polished stainless steel finish and the set’s metrological integrity. For formal calibration certificates, the set’s OIML E1 status is accepted as a high-grade reference by many testing authorities.
