PURPOSE: To prevent contamination with electrolyte or pressure leakage even upon temperature rise through a simple structure dispensing with pressure balance mechanism. CONSTITUTION: A glass tube 1 disposed in the center of an oxygen dissolved electrode is fixed, at the tip thereof, with an anode 2 and an electrolyte container 3 is disposed on the outer circumference thereof. An oxygen permeable membrane 6 is stretched at the tip of the electrolyte container 3 which is then filled with an electrolyte. A cathode output lead 10 is connected with the cathode, i.e., the electrolyte container 3, and an anode output lead 11 is connected with the anode. Potential between the output leads is measured and the concentration of dissolved oxygen is determined. |
