Abstract

A filter for an electrochemical measuring cell with a filter housing and a filter material contained therein is improved, with a simple design, such that interfering gas components cannot reach the measuring cell from the gas mixture. This is accomplished by the filter housing being formed of a porous, gas-permeable material.
