GALVANIC CELL OXYGEN ANALYZER

摘要

OXYGEN ANALYZER A galvanic cell type oxygen analyzer for analyzing oxygen in a gas rich in hydrogen comprising an anode protecting electrode formed using gold, silver or rhenium. Employment of a noble metal of this kind as a material for the anode protecting electrode enables a reduction in the noise level caused by dissociation and adsorption of hydrogen and permits a stable output to be maintained. Also disclosed is a galvanic cell type oxygen analyzer wherein gold, silver or rhenium is employed as a material for a water electrolyzing electrode of a standard gas generator for water electrolysis type calibration.
