Abstract
The invention relates to an ionization vacuum measuring cell () comprising an evacuable housing () with a measurement connection for a vacuum to be measured at an end portion; a measurement chamber () in the housing (), said measurement chamber being fluidically connected to the measurement connection, wherein the measurement chamber () is designed as a replaceable component; and a first and a second electrode () in the measurement chamber (), said electrodes being substantially coaxial to an axis and being arranged at a distance from each other. The measuring cell further comprises an electrically insulating and vacuum-tight feedthrough () for an electric supply to the second electrode () and a magnetization assembly which is designed to generate a magnetic field in the ionization chamber. According to the invention, the measurement chamber (), in particular at least one of the electrodes (), comprises a magnetic material.
