Accuracy is what matters most
When choosing a scale, especially in industry or the transportation sector, accuracy becomes not an advantage but a necessity. Metrological parameters indicate how accurately a scale can measure mass or weight, and not only operational efficiency but also legal compliance with regulations depend on them.
The most important metrological parameters:
-
Scale class (according to OIML R76): indicates the permissible error. The most commonly used classes are III (standard) and IIII (lower accuracy).
-
e-value (verification interval): the smallest change in mass that the scale can record, for example 5 kg or 20 g.
-
d value (display division): the smallest change in readings that is visible on the display.
-
Maximum weighing range ( Max ): The largest load that the scale can reliably measure.
-
Minimum load ( Min ): The smallest load that the scale must measure accurately.
-
Permissible errors : depends on the scale class and load. For example, for class III scales with a load of 30 t, the permissible error may be ±5 kg.
What are scale classes?
The accuracy of scales is classified into 4 main classes:
| Class | Description | Area of application |
|---|---|---|
| I | Very accurate | Laboratories |
| II | Accurate | Pharmacies, research equipment |
| III | Medium accuracy | Industry, transport |
| III | Simple | Warehouses, construction |
Transport and industrial scales are usually class III , and some are class IIII , especially when mobile or axial versions are used.
The importance of verification
Scales used in trade or official measurements must have metrological verification (marked with the "M" mark). This ensures that the equipment operates according to established standards and the results will not conflict with legal regulations.
