    • The electromotive force of a standard liquid for correction is measured. Both before and after this measurement, the electromotive force of a reference liquid is measured at least once. A calibration curve is prepared based on the resultant data. The calibration curve is used to convert the electromotive force difference between a test liquid (the ion concentration of which is to be measured) and the reference liquid. Both before and after the measurement of the electromotive force of the test liquid, the electromotive force of the reference liquid is measured at least once. By so doing, the electromotive force difference between the test liquid and the reference liquid is obtained. The ion concentration of the test liquid can be detected accurately by plotting the electromotive force difference against the calibration curve.
    • 测量用于校正的标准液体的电动势。 在该测量之前和之后,测量至少一次参考液体的电动势。 基于得到的数据准备校准曲线。 校准曲线用于转换测试液体(其离子浓度要测量)与参考液体之间的电动势差。 在测试液体的电动势之前和之后,基准液体的电动势至少测量一次。 通过这样做,可以获得测试液体和参考液体之间的电动势差。 可以通过将电动势差与标定曲线相对应地精确地检测出测试液的离子浓度。
