Устройство для измерения концентрации кислорода в газах, содержащее потенциометрическую твердоэлектролитную ячейку, конструктивно выполненную из двух камер, разделенных твердым электролитом в виде мембраны с нанесенными на ее поверхность электродов из платины, и измеритель ЭДС, подключенный к платиновым электродам, отличающееся тем, что, с целью повышения точности измерения, оно содержит кулонометрическую твердоэлектролитную ячейку и источник инертного газа с известной концентрацией кислорода, причем анализируемый газ пропускают через одну камеру потенциометрической твердоэлектролитной ячейки, а инертный газ после кулонометрической твердоэлектролитной ячейки пропускают через другую камеру, при этом концентрацию кислорода в анализируемом газе определяют по концентрации кислорода в инертном газе и концентрации кислорода, создаваемой током переноса кислорода через кулонометрическую твердоэлектролитную ячейку, с учетом прошедшего через нее расхода инертного газа, при условии, что ЭДС на электродах потенциометрической твердоэлектролитной ячейки равна нулю.A device for measuring the concentration of oxygen in gases, containing a potentiometric solid electrolyte cell, structurally made of two chambers separated by a solid electrolyte in the form of a membrane with platinum electrodes deposited on its surface, and an EMF meter connected to platinum electrodes, characterized in that, for the purpose of To increase the measurement accuracy, it contains a coulometric solid electrolyte cell and a source of inert gas with a known oxygen concentration, and the analyzed gas is passed through through one chamber of the potentiometric solid electrolyte cell, and the inert gas after the coulometric solid electrolyte cell is passed through another chamber, while the oxygen concentration in the analyzed gas is determined by the oxygen concentration in the inert gas and the oxygen concentration created by the oxygen transfer current through the coulometric solid electrolyte cell, taking into account the passage through the inert gas flow rate, provided that the EMF on the electrodes of the potentiometric solid electrolyte cell is zero.
