Abstract

Procedimiento de medición del contenido de oxígeno de una mezcla gaseosa, tal como una atmósfera, del tipo en que se provoca, en una cámara de medición, la combustión de un gas o de un vapor combustible en una muestra de la mezcla gaseosa por medio de un elemento activador de combustión, tal como un elemento catalítico, introducido en un circuito de medición que suministra una señal de medición que varía en función de la temperatura alcanzada por el elemento de calentamiento.
