FIELD: medical equipment, intended for determining the concentration of hydrogen ions(pH) in biological media. SUBSTANCE: the pH-probe uses measuring antimony electrodes in the form of rings rigidly secured on thin-walled bushes, a hose pulled on the bushes, chlorsilver comparison electrode placed in a non-metallic casing consisting of a foundation and cap with a hole, and conductors running inside the hose and connecting the electrodes to a connector. The casing of the chlorsilver electrode uses one more cap with a hole connected in succession to the first cap through a flexible tube pulled on the caps, and the cavities of the second cap and flexible tube are filled with non-metallic porous material impregnated with a solution of potassium chloride. EFFECT: enhanced accuracy. |
