Custom-made precision weights and storage boxes

Precision weights are available individually or in special boxes for easy storage and transportation. In accordance with your specifications, we can also put together full sets of custom-made precision weights, packed in a suitable box.

 

According to the OIML, the International Organisation of Legal Metrology, precision weights up to 50 kg are divided into six categories:

  • M2 Trade precision weights as counterweights on mechanical balances
  • M1 Precision weights for the verification of trade scales
  • F2 Test weights for the verification of laboratory balances
  • F1 High precision weights for analytical balances
  • E2 Weight standards, used by metrological services
  • E1 Highest accuracy class
