A measurement head is provided for a device for measuring the concentration of at least one gas, in particular oxygen. A gas sample a measurement element () is arranged in the region of an opening on a circuit board (). To convey gas a duct () is formed in each of two metal bodies, which surround the measurement element () and serve as magnetic poles. During operation of the measurement head the gas sample flows substantially perpendicularly, first through one of the metal bodies (), and then through the opening () on a side of the measurement element () facing the opening and emerges again through the other metal body ().
