Class M1 Precision Calibration Weight

Our Class M1 precision weight is ideal for use with commercial and industrial balances, compliant with verification class III. Manufactured in A3 steel to international standards, this weight guarantees reliable and precise resolution. It is specifically designed for the adjustment and verification of electronic balances, ensuring exact measurements within specified tolerances.

The International Organisation of Legal Metrology (OIML) sets the metrological requirements that weights must meet, as outlined in the OIML R111 standard. These include criteria for accuracy, manufacturing materials, and storage. Weights are classified into different tolerance classes, each with a maximum permissible error.

Availability: We offer weights in various mass values and technical features, along with the ENAC M1 mass certificate. Options range from lighter to heavier weights, adapting to diverse calibration needs.
