Marking of E2 Weights

According to OIML R111-1:2004, weights of class E2 are not marked with their nominal value or with unit information. For differentiation, weights of the same nominal value that occur more than once in weight sets can be marked with dots or stars.

In addition, up to three customer-specific user markings, such as characters, letters or numbers, can be applied. This allows the weights to be clearly identified as test or measuring equipment and better integrated into internal test equipment management.

These user markings can be specified individually when ordering.

Weight sets and cases

All weight sets include gloves, two brushes and two tweezers; sets up to 50 g come without the big tweezers, the big brush and the gloves.
