KERN 313-06 weight set (OIML E2) — 1 mg–1 kg, polished stainless steel

The KERN 313-06 weight set is a class E2 calibration mass kit designed for high‑precision balance verification and quality control in laboratories and industrial metrology.

• OIML class E2 certified accuracy
• Nominal range 1 mg–1 kg
• Polished stainless‑steel masses
• Supplied in wooden case with inner plastic tray

Precision that supports reproducible measurement results

The set delivers OIML E2 accuracy across a broad 1 mg–1 kg range, permitting consistent verification of analytical and precision balances. Certified class E2 indicates tight tolerances for individual masses, which reduces measurement uncertainty during routine checks and instrument qualification. This translates into fewer re‑tests, more efficient calibration cycles and a measurable improvement in process reliability for laboratories and quality departments.

Robust materials and organised storage for safe handling

Each mass is manufactured from polished stainless steel, offering corrosion resistance and a smooth surface finish that minimises contamination and handling marks. The ergonomic button‑shaped masses simplify positioning on sensitive balance pans and reduce the risk of tipping. Milligram weights are stored in a separate plastic tray inside the wooden case, which protects the smallest masses from dust and abrasion — a practical detail that preserves long‑term accuracy and simplifies day‑to‑day use.

Compliance, traceability and practical suitability for testing routines

The kit supports traceable verification routines where documented conformity to international standards is required. The combination of class E2 certification and a comprehensive nominal range makes the set suitable for laboratories, calibration service providers and production quality control where documented measurement capability is essential. Manufactured by KERN in Germany, the set is designed for dependable performance in regulated environments and for integration into established calibration workflows.

FAQ

What accuracy class does this set meet and what does that mean for calibration?
The KERN 313‑06 weight set meets OIML E2 accuracy class; this means the masses conform to narrow tolerance bands suitable for precise verification of analytical and precision balances, reducing measurement uncertainty in routine checks.

Is the set suitable for laboratory use and routine balance verification?
Yes — the combination of 1 mg–1 kg nominal values and class E2 conformity makes the set well suited to laboratory environments and regular balance verification tasks where documented traceability is required.

How are the smallest masses protected during storage and transport?
Milligram masses (1 mg–500 mg) are supplied in a separate plastic case inside the wooden outer case to prevent contact damage and contamination, supporting long‑term stability of the smallest units.

What advantages does polished stainless steel provide for calibration masses?
Polished stainless steel offers corrosion resistance and a smooth surface that minimises particulate adhesion and handling marks, which helps maintain mass integrity and repeatable measurement results over time.

Can this set be used for official calibration certificates?
The set’s OIML E2 classification and manufacturer documentation make it suitable as a reference for in‑house verification and for use in accredited calibration procedures where class E2 masses are allowed
