Weight set 303-05 — OIML E1, 1 mg–500 g, polished stainless steel (KERN)

A Weight set 303-05 engineered for high-precision calibration and verification of analytical and precision balances in laboratories and quality control environments.

• OIML class E1 accuracy
• Range 1 mg – 500 g
• Polished stainless steel buttons

High-precision calibration for compliant measurement

The set delivers OIML E1 class accuracy, providing a stable reference for the most demanding calibration tasks. Supplied masses are suitable for routine verification and adjustment of analytical balances, supporting traceable results and conformity with regulatory requirements. By using certified calibration masses, measurement uncertainty is reduced and quality assurance processes gain robustness.

Durable materials and careful handling for long service life

Manufactured from polished stainless steel, the masses resist corrosion and surface wear, preserving nominal values over time. The button-shaped design facilitates handling and minimises contamination during use. The milligram range is supplied separately in a separate plastic case, which eases organisation of the smallest masses and protects them from damage and dust when not in use.

Improved workflow reliability in production and laboratory settings

A calibrated mass set simplifies verification routines and shortens downtime during instrument checks, ensuring continuity in production or testing lines. The compact arrangement in a wooden case keeps all components secure for storage and transport, supporting efficient metrology procedures and helping maintain internal audit trails and traceability records.

Practical storage and transport that protect precision

The wooden case provides robust protection and a dedicated place for each mass, reducing handling errors and the risk of loss. Clear organisation and marked slots streamline daily routines, while the durable construction of the case contributes to safe storage between calibrations. The set is designed to be a dependable reference within equipment fleets and calibration benches.
