Abstract: Prior to measuring the concentration of a nonelectrolyte in an electrolyte solution, the electric conductivity of a mixed solution containing electrolytes and the nonelectrolyte is previously measured so as to determine the correlation between the electric conductivity and the concentration of the nonelectrolyte as to the same system. The concentration of the nonelectrolyte in the mixed solution can be determined from the electric conductivity obtained by measuring the mixed solution, based on the correlation.

Abstract: A pH measuring electrode having a sensor film (3) which is sensitive to hydrogen ion (H⁺) in solution and method of manufacturing it are described. The electrode has a sensor film (3) of metal oxide deposited on an electrically conductive support (1) so that the sensor film can be miniaturized. Also, in a further embodiment, the electrode includes a porous film (23) of insulation material coated on the surface of the metal oxide sensor film so that the sensor film is not affected by any interferring substances.
