Abstract

A measuring assembly is described for studying gaseous media, in which a measuring cell (20) connected to a circuit board (40) is clamped into a receptacle (10). The receptacle (10) includes a base plate (11), a pressure plate (30), arms connecting base plate (11) and the pressure plate (30) with each other, i.e., a stud bolt (13) and a connecting arm (14), as well as a pressure spring (16) acting on the pressure plate (30). The pressure plate (11) is supplemented by a chamber cover (15) so as to form a gas chamber (17). Preferably, a filter (50) is located between the base plate (11)/chamber cover (15) and the measuring cell (20).
