E1-knob-weights-Series
Reference mass standards and weights of class E1: adjustment, testing and calibration instruments within the quality assurance of balances with more than 1 000 000 steps according to DIN EN ISO 9001 ff., for the calibration of weights of class E2 according to OIML R111, and for high-precision weighing or comparisons on mass comparators.
E1 mass standards are used, among other applications, in quality assurance, calibration laboratories and applications with high requirements for measuring accuracy, stability and traceability. They can also be used for the calibration and verification of E2 weights according to OIML R111.
According to OIML R111-1:2004, weights of class E1 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.
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.
