Abstract
A polarographic cell for measuring partial pressure of oxygen in a fluid in which the detector electrode and the reference electrode are immersed in an electrolyte at least partially absorbed in a rigid insulating material.
Claims5
In a polarographic cell particularly adapted for the measurement of the partial pressure of a gas in a fluid comprising a detection electrode and a reference electrode immersed in an electrolyte and an insulating membrane, permeable to the gas being measured, separating the electrodes and the electrolyte from said fluid, the improvement wherein the electrolyte is at least partly immobililized by absorption in a rigid, insulating, porous material selected from the group consisting of sintered glass and sintered ceramic material and at least the detection electrode is in the form of a coating on the surface of said rigid material, said coating being thinner than said rigid material.
