Show affiliationsA mass comparator for 1 kg weights has been designed and built at the BIPM based on our experience with a prototype flexure-strip balance named FB-1. The flexure-strip balance FB-2 is fully automated and mainly used for research. It consistently achieves a repeatability of weighings in air or in vacuum of 1 kg artefacts at least ten times better than that obtainable with the best knife-edge balances. The aim of this paper is to describe the design and capabilities of the FB-2, drawing on theoretical studies already published. Finally, results obtained with the FB-2 are given to illustrate its metrological possibilities.
