Single Weights



Example of optional laser marking

Weights in class E2 according to OIML recommendation R111 and suitable for legal metrology and industrial applications. The accuracy class E2 allows the use of these weights for checking the calibration of scales and class I instruments up to 500.000e.
Ideal for the verification of weighing instruments in ISO quality regime.


  • In compliance with the OIML - R111 recommendation;
  • E2 precision class;
  • in highly polished austenitic stainless steel;
  • accredia (ea) calibration certificate upon request;
  • available with single or multiple case made of plastic or wood (case is compulsory for certified weights).


  • The laser marking service is useful to identify each weight or mass individually. More specifically:
    - The marking allows easier identification and traceability of each weight or mass;
    - It is perfectly smooth, does not remove material from the weight and does not affect the surface, thus avoiding dust deposit;
    - It is customisable, according to the requirements of the companies.
    In addition:
    - It remains unchanged over time;
    - It can be performed on previously purchased masses and weights, of all accuracy classes, from 1 g to 20 kg;
    - It is perfect for pharmaceutical industries and laboratories.

    Below you can see a preview of the calibration certificate. Please pay special attention to point 2. “Required information”, data to be communicated to the laboratory when requesting calibration.
