Abstract

An electrochemical measuring apparatus may be charged with an option of several media by providing a feeder part with the respective media connections, and by guiding a piece of pipe in a bore, which is sealed off and is movable relative to this feeder part. On its end facing away from a measuring chamber in the apparatus, the piece of pipe has a connection for additional media. Besides, it carries at least one circumferential bore which may be brought to coincide with at least one of the input openings into the bore connecting to the feed lines, by means of a relative motion - preferably controlled via a stepping motor - between the pipe piece and the above bore.
