摘要： A simplified, rigorous and accurate method of measuring pH of an analyte solution with extreme precision, which does not cause errors against actual pH through compensating a pH variation by a liquid temperature or a concentration of potassium chloride of an internal liquid in a glass electrode or a reference electrode when pH is measured with respect to various analyte solutions such as a sample solution having a high concentration of salts, a sample solution contaminated with salts and a sample solution having a low concentration of salts.
