In this paper we address several conceptual and historical aspects of the quantum Hall effect. We argue that this effect offers a variety of perspectives for philosophical reflection, from the generation of theoretical entities to the epistemology of experimentation. The exposition attempts to maintain a certain sensitivity to the historical dynamics around the issue, considering at the same time its metrological implications for specific quantum areas. Given the vast scientific literature on the subject, a cut is made in order to rescue some meaningful profiles of the phenomena associated with this effect.
