First Results Using the Planck-Balance

A table top version of a Kibble balance called the Planck-Balance has been developed by the Physikalisch-Technische Bundesanstalt (PTB) and the Technische Universitat Ilmenau (TUIL). After one year of development, the first measurement results were obtained. The mass of a 10 g mass standard has been determined with a relative type A uncertainty of 3 × 10
^-7
. A preliminary uncertainty budget shows a relative combined measurement uncertainty of 1 × 10

. This paper gives a brief overview of the concept of the balance, its measurement principle, its results and a preliminary uncertainty budget.
