FIELD: physics.
SUBSTANCE: method intended for maintaining preset oxygen pressure in closed space accommodating oxygen source and/or absorber, using oxygen partial pressure pickup, electrochemical pump with membrane from solid oxygen conducting electrolyte with porous electrodes applied thereon and connected to power supply, and control unit, consists in that electrical voltage feedback is generated in said power supply. Power supply output voltage to be fed to pump electrodes is set by adjustment law defined by electric relationship.
EFFECT: higher accuracy of oxygen partial pressure adjustment.
