KERN 344-05 Calibration weight set (OIML class M1, 1 g–500 g)

A KERN 344-05 calibration weight set designed for the verification and routine calibration of laboratory and workshop balances, supplied as a button‑shaped set in a wooden case

• OIML class M1 accuracy
• Range 1 g–500 g in button form
• Fine‑turned stainless‑steel weights
• Supplied in a wooden case

Ensure measurement reliability with class‑defined accuracy

The set is specified to OIML class M1, which defines tolerance limits suitable for routine verification and adjustment of precision balances. This classification provides a reliable basis for comparing and adjusting instruments, helping to reduce measurement uncertainty and streamline conformity checks. By using a set with a defined nominal range of 1 g–500 g, laboratories and workshops benefit from a single, compact solution for a wide span of common calibration tasks, minimising handling time and procedural complexity.

Durable materials that maintain accuracy under frequent use

Each mass is manufactured from finely turned stainless steel, a choice that combines surface precision with corrosion resistance for long service life. The button shape improves handling and positioning on balance pans, while the fine turning ensures consistent contact geometry and repeatable results. These construction choices reduce the need for frequent replacement and support stable performance under regular use, contributing to operational efficiency and lower total cost of ownership over time.

Practical storage and straightforward handling for daily workflows

The complete set is delivered in a wooden case that keeps the masses organised, protected and ready for transport between workstations. The compact packaging and clear nominal labelling speed up selection and reduce risk of contamination during routine procedures. With a total set weight of approx. 1.71 kg, the collection remains portable yet substantial enough for secure storage. The combination of classification, material and case design simplifies daily calibration routines and supports traceable record‑keeping for quality management systems.
