| Abstract: | A new wolfram oxide-coated wire microelectrode for the determination of pH value is described. The results showed a satisfactory response to hydrogen ion in the pH range of 2 to 12 with a Nernst slope of 55mV/pH. The microelectrode has been applied to the determination of pH value in the base of the human tooth with satisfactory results. |
