Abstract

667,471. pH Measuring apparatus. INGOLD, W., and KUBLI, H. Feb. 24, 1950 [Feb. 25, 1949], No. 4827/50. Class 37. In a pH measuring cell the glass electrode with built in reference electrode A2, the electrostatic shield and the second reference electrode A1 are connected together to form an inseparable one piece unit. The glass electrode comprises an outer tube G1 spaced from an inner tube G2 and the electrostatic shield (not shown) occupies the space between these two tubes and is either a metal sheath, for example, of mecury, copper or silver, or is a well conducting salt solution. A third and innermost tube G3 encloses the builtin reference electrode A2 which contacts a selected reference solution within tube G2. The latter opens into a glass sphere E to which the pH sensitive membrane M is secured. The glass sphere E is penetrated by the tip S of a capillary tube K which via branch tube G4 is filled with the second chosen reference solution in contact with the electrode A1 in tube St. The electrostatic shield between the tubes G1, G2 is connected to the screening H on the cable lead Ka.
