Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Generator of oxygen-containing testing mixes Semchevsky А.К., Pinsoukhovich R.L, Kouznetsov B.F. The article deals with the obtaining of the analytical equation of the model of generator electrolyte cell of generator of the oxygen-containing testing mixes. The obtained equation connects oxygen concentration according to the length of the cell with its physical and constructive data. The experimental researches on the developed laboratory stand, confirm the adequacy of the constructed model to the real cell properties. The cell has been used in the development of installation “Biryuza” for gas mixes preparation with the set content of oxygen in a range of oxygen concentration from 0,001 … 1 %.
