A method is disclosed for measuring a profile of a reflecting face of an end (2) of a pipe section. An electrical field is generated between the face and suspended particles (19) in the ambient air of the face. The particles (19) are attracted to the face by the electrical field and matt-finishing the face. The face is then sensed with a laser beam (16) and scattered light (17) is reflected by the face and measured by a sensor (11), thereby determining a face profile.
