Weight set 343-05 — OIML class M1, 1 mg–500 g, stainless steel

The Weight set 343-05 is a precision calibration set in button form designed for balance verification and legal checks across laboratories and workshops.

• OIML class M1 accuracy for legal calibration
• Nominal range 1 mg–500 g, dual-purpose set
• Finely turned stainless-steel button weights
• Supplied in protective wooden case

Precision and compliance for dependable measurements

The set is manufactured to OIML M1 standards, ensuring traceable and legally compliant mass values for a broad range of balances. With a nominal range of 1 mg–500 g, the collection covers micro to medium scales, reducing the need for multiple separate sets and shortening calibration cycles. The use of stainless steel that is finely turned secures dimensional stability and low surface contamination, which benefits repeatability during routine verifications. This technical conformity supports efficient quality control and reduces uncertainty in measurement workflows.

Design and handling that protect calibration integrity

Button-shaped weights offer a low-profile footprint and make placement on balance pans straightforward while minimising handling-induced errors. The set is supplied in a robust wooden case that organises components neatly and protects them from knocks and dust. Notably, the milligram weights are stored in a separate plastic insert, which simplifies access for micro-adjustments and prevents cross-contamination between sizes. These storage solutions preserve the set’s condition and facilitate repeatable results during on-site checks or in-house laboratory procedures.

Versatile application and reliable provenance

Branded by KERN, the set suits calibration tasks for precision balances used in industrial metrology, educational labs and quality assurance departments. The comprehensive range from microgram classes up to hundreds of grams streamlines verification routines across multiple instruments. Originating from Germany (DE) and delivered as a complete kit, the set supports systematic calibration planning and minimises downtime caused by missing mass values, thereby contributing to continuous production quality and documented measurement chains.

FAQ

What balances can be calibrated with this set?
The KERN weight set 343-05 is suitable for calibrating precision balances covering the range from 1 mg to 500 g, making it appropriate for laboratory and workshop verification tasks.

What does OIML class M1 mean for accuracy?
OIML class M1 specifies legal and technical tolerances appropriate for many laboratory and industrial calibration tasks; the KERN 343-05 meets these tolerances for reliable measurement uncertainty control.

How are the smallest weights protected during storage?
Milligram weights included in the set are kept in a separate plastic insert within the wooden case, which reduces handling and protects the smallest masses from contamination and damage.

Is the set corrosion-resistant for frequent use?
The masses are made from finely turned stainless steel, offering good resistance to oxidation and surface wear, which helps maintain mass stability during repeated use.
