Abstract
L'invention concerne un procédé et un dispostif de dosage de l'oxygène dans un mélange gazeux, tel qu'une atmosphère. On modifie un dispositif explosimètre à pont de mesure comportant un filament doseur D dans une chambre de mesure 1, pour introduire dans la chambre de mesure remplie d'un échantillon d'un mélange gazeux, tel qu'une atmosphère, du gaz combustible, tel que du butane, par un tube 35, en débit tel que sa concentration provoque une déviation maximale possible Smax du signal de mesure S, laquelle déviation Smax est prise comme représentative de la teneur en oxygène de l'échantillon du mélange gazeux. L'invention s'applique au dosage de l'oxygène dans l'atmosphère.
