ECO block weight, Class M3 – 50 kg (KERN)

The ECO block weight is a compact calibration weight designed for routine verification of industrial and workshop scales, offering a dependable reference mass for everyday metrology tasks.

• OIML class M3 certified accuracy
• Durable painted cast iron construction
• Compact block design for stable placement
• Nominal value 50 kg with 25 g tolerance

Dependable reference mass for routine verification

The ECO block weight serves as a straightforward reference for scale checks where robustness and repeatable performance are required. With OIML Class M3 certification and a nominal mass of 50 kg, the unit supports routine conformity checks and internal quality control. The declared tolerance 25 g gives a clear quantitative limit for permissible deviation, enabling technicians to verify that a scale remains within expected performance bands and to document results for traceability and audit purposes.

Built for workshop environments and practical handling

Constructed from painted cast iron, the block design delivers stability during placement and minimises tipping or rolling compared with cylindrical weights. The Block Eco format concentrates mass in a low-profile form, which simplifies positioning on load platforms and reduces the risk of accidental displacement. As an individual calibration weight, it is suitable for industrial settings where durability matters; the robust finish reduces corrosion risk and makes routine cleaning straightforward, supporting long service life under regular use.

Integration, documentation and operational benefits

Using a clearly identified calibration weight reduces downtime during verification routines and streamlines calibration paperwork. The single calibration weight format limits handling complexity and helps maintain a consistent reference point across shifts. With manufacturer data such as GTIN available for inventory and asset management, procurement and stores teams can track stock and ensure continuity of supply. Choosing a standardised block weight supports efficient workflows and contributes to reliable measurement results across production and inspection stations.

FAQ

What does OIML Class M3 mean for its use?
OIML Class M3 indicates a defined level of allowable deviation appropriate for routine verification tasks; the ECO block weight is intended as a practical reference mass for industrial and workshop scales rather than high-precision laboratory calibrations.

Can the ECO block weight be used on any scale with a 50 kg range?
The ECO block weight (KERN, SKU 366-79) provides a 50 kg nominal mass for verification; suitability depends on the scale’s capacity and intended tolerance checks, so selection should match the device’s verification requirements.

How should the painted cast iron weight be maintained?
Routine maintenance for the painted cast iron finish consists of gentle cleaning to remove debris and dry storage to minimise corrosion risk; avoid aggressive solvents that could damage the coating.

Is the declared tolerance sufficient for routine quality control?
For many workshop and industrial applications, the 25 g tolerance of this OIML M3 weight offers a clear, measurable criterion to confirm that a scale remains within acceptable limits and to support documented checks.

How does the block design improve handling during verification?
The low-profile Block Eco shape concentrates mass close to the platform, improving stability and simplifying positioning, which reduces handling time and the likelihood of measurement disturbance.
