Abstract

A probe arrangement, in the case of which a probe is arranged within a tubular housing, wherein the tubular housing has at least one process window open to the process medium, and at least one functional element is secured on the probe and surrounded by the process medium. In order to suppress a taking along of the process medium during transfer of the functional element from the measured medium into a rinsing chamber, the tubular housing includes at least one treatment window open opposite the probe (3), preferably for washing, rinsing and/or calibrating the functional element, wherein the functional element is movable between the process window and the treatment window, and, during the measuring in the process medium, the at least one functional element is arranged approximately coincident with the at least one process window of the housing.
