Calibration Weight Set 303-03 — OIML E1, 1 mg–100 g (KERN)

The Calibration Weight Set 303-03 is a precision weight kit for laboratory and industrial balance calibration, designed for traceable mass verification and routine verification tasks.

• OIML class E1 certified precision
• Range 1 mg–100 g with mg subdivision
• Polished stainless steel button weights
• Supplied in a wooden storage case

Traceable accuracy for laboratory and production control

The set provides OIML class E1 accuracy across a 1 mg–100 g span, meeting the stringent requirements for reference and calibration work. The smallest milligram weights are grouped separately, enabling fine adjustments and comparisons with minimal measurement uncertainty. Polished stainless steel construction ensures dimensional stability and corrosion resistance, while the button shape supports secure placement on balance pans. For metrology and quality departments this combination reduces calibration time and supports reliable verification routines.

Practical design that supports repeatable handling

A thoughtful layout and durable housing simplify daily use: the main weights are organised for direct access and the milligram weights (1 mg–500 mg) are stored in a separate plastic case to prevent accidental damage. The wooden storage case protects components from contamination and mechanical shock during transport or storage. The robust finish and ergonomic form of the weights facilitate consistent placement, which in turn lowers operator-induced variation and improves reproducibility in routine checks.

Compliance, documentation and fit for purpose

Built to the OIML E1 specification, the set is suitable where the highest class of reference weights is required for calibration chains and conformity assessments. Each set supports traceable calibration regimes and internal quality control plans, helping to maintain certification and meet audit requirements. Delivered by a trusted supplier, the kit complements calibration workflows in testing labs, research facilities and high-precision industrial environments while supporting a clear documentation trail.

FAQ

Are these weights suitable for ISO/IEC 17025 calibration laboratories?
The KERN Calibration Weight Set 303-03 meets OIML class E1 requirements and is suitable as reference standards within accredited calibration procedures when accompanied by appropriate calibration certificates.

What materials are the weights made from and why does that matter?
Weights in the 303-03 set are made from polished stainless steel, providing corrosion resistance and dimensional stability for reliable long-term use in laboratory environments.

How is the milligram range supplied and protected?
The milligram weights (1 mg–500 mg) included with the calibration set are supplied in a separate plastic case to prevent handling damage and contamination of the finer masses.

Can the set be used for routine balance checks in production?
Yes, the 1 mg–100 g range and the E1 accuracy class make the set suitable for high-precision balance verification and critical production checks where minimal measurement uncertainty is required.

Is the KERN 303-03 supplied with a certificate?
Specific delivery contents depend on the selected configuration; please consult Metav Werkzeuge for details on calibration certificates and options for factory or DAkkS traceable documentation for the 303-03 set.
