KERN 343-07 weight set (OIML M1, 1 mg–2 kg)

The KERN 343-07 is a precision weight set intended for calibration and verification of laboratory and industrial balances, supplied as button‑form weights in a wooden case for secure storage and transport.

• OIML class M1 accuracy
• Stainless steel, fine‑turned weights
• Wooden case with separate milligram tray

Reliable accuracy for routine calibration

The set meets OIML M1 requirements and covers a nominal range of 1 mg–2 kg, making it suitable where consistent repeatability and traceable checkpoints are required in production and testing environments. The classification indicates a balance between laboratory‑grade performance and practical workshop use, offering measurable improvement in calibration routines compared with non‑classified masses. The fine‑turned stainless steel construction reduces surface irregularities and long‑term drift, maintaining mass stability during frequent handling.

Practical layout and secure storage reduce handling errors

Designed with a wooden case and compact, ergonomic weights in button shape, the set organises components for efficient workflow and minimal handling time. The milligram range (1 mg–500 mg) is supplied in a separate plastic tray to protect the smallest masses from contamination and abrasion, simplifying changeover during successive calibration steps. Clear separation of small and large weights helps preserve measurement quality and speeds up routine verifications on benches and in calibration labs.

Materials and handling that protect measurement integrity

Fine‑turned stainless steel resists corrosion and provides a hard, smooth surface that lowers the chance of contamination or dimensional change; this supports repeatable results over prolonged use. For best results, handle masses with tweezers or gloves to avoid oils and particulates that alter mass values. The set’s construction and packaging minimise exposure to environmental factors, helping to preserve the tare and ensure consistent performance between recalibrations.

Built for traceability and industrial application

Manufactured to be used in calibration procedures across workshops and inspection stations, the set combines a wide nominal range with robust casing for secure transport and storage. The origin in Germany and the clear SKU and identifiers support traceability in procurement and quality systems. Robust materials and considered packing mean the set is ready for frequent use where reliable reference masses are required for process control, acceptance testing and routine balance checks.

FAQ

What does OIML class M1 mean for daily calibration tasks?
OIML class M1 defines a recognised tolerance class suitable for routine calibration and verification of non‑reference balances; the KERN 343-07 set provides a balance between precision and practical workshop use.

Are the smallest weights protected during storage?
Yes, the milligram weights (1 mg–500 mg) are supplied in a separate plastic tray inside the wooden case to reduce contamination and handling damage.

What material are the weights made from?
The weights are made from fine‑turned stainless steel, chosen for surface stability, corrosion resistance and long service life.

Is the set suitable for use in production and laboratory environments?
The comprehensive 1 mg–2 kg range and OIML M1 classification make the set appropriate for calibration work in both laboratory and industrial settings where reliable checkpoints are required.

How is traceability and identification provided?
The set includes clear identifiers such as SKU 343-07 and GTIN 4045761007567 to support procurement records and traceability in quality systems.
