KERN 344-04 calibration weight set — OIML Class M1, 1 g–200 g

The KERN 344-04 calibration weight set is a compact, laboratory-grade set of button-style weights for routine calibration and verification of balances in workshops and inspection labs.

• OIML Class M1 accuracy
• Range 1 g–200 g
• Fine-turned stainless steel
• Supplied in a wooden case

Reliable routine calibration with OIML Class M1

The set delivers consistent calibration performance thanks to its OIML Class M1 specification, which defines permissible deviations for routine and industrial verification. For everyday balance checks and spot verifications, the declared accuracy reduces uncertainty and helps maintain measurement traceability across serial testing. The calibrated mass range 1 g–200 g covers the most common test points used in workshop and production environments, enabling efficient verification without overcomplication.

Durable materials that preserve accuracy over time

Each weight is fine-turned from stainless steel, a material choice that combines dimensional stability with corrosion resistance. The precision-machined surfaces reduce contamination and handling marks, helping to retain nominal values during repeated use. The button-shaped design supports easy handling with tweezers or gloves and minimises contact area, which in turn reduces the risk of wear and transfer of oils. Such construction supports longer intervals between checks and contributes to predictable measurement behaviour in daily operation.

Practical protection and straightforward storage

Delivered in a fitted wooden case, the set is ready for transport between workshop and inspection bench while remaining protected from shocks and dust. The case organises the individual masses for quick selection during calibration routines and aids safe storage when not in use. Compact dimensions and clear labelling support fast workflows and reduce the time spent preparing test equipment, improving overall process efficiency in production and maintenance cycles.

Integration into calibration workflows

Designed for compatibility with a wide range of laboratory and industrial balances, the kit suits technicians responsible for routine verification, incoming inspection, or maintenance. The combination of stainless steel construction and OIML Class M1 accuracy provides a balanced mix of durability and precision ideal for standardised checks. Where traceable standards are required, this set functions as a practical reference for daily control measurements within quality systems.

FAQ

What does OIML Class M1 mean for daily calibration?
OIML Class M1 defines the permissible tolerance band for routine and industrial mass standards; the KERN 344-04 set meets these limits and is therefore suitable for regular balance checks and control measurements.

Is the material corrosion resistant?
Yes, the weights are made from fine-turned stainless steel, offering good resistance to corrosion and ensuring stability in workshop and laboratory conditions.

Does the set include a storage case?
The set is supplied in a fitted wooden case that protects the masses and organises them for quick access during calibration routines.

Can this set be used for precision laboratory calibrations?
The kit is tailored for routine verification and industrial checks under OIML Class M1; for higher-accuracy laboratory calibrations, classes with tighter tolerances may be required.

How is handling simplified by the weight design?
The button form and smooth, precision-machined surfaces allow handling with tweezers or gloves, reducing direct contact and helping to preserve nominal mass values.
