Abstract
An oxygen gas analyzing device in which gas sampled from a flue is analyzed without the need of an external driving source. A sampling tube protrudes into a flue through a wall thereof. A partition board divides the gas sampling tube extending from the protruding end of the tube forming gas flow-in and flow-out paths. A solid electrolytic element is positioned in a ceramic tube having one end open to the outer end of the gas sampling tube. A heater is provided in the walls of the ceramic tube.
