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.

摘要： The purpose of the present invention is to measure pH of a sample with high accuracy in a pH sensor array, without the use of a glass reference electrode. Each time that a sample is measured, the potential Vrm of the sample is identified, and the identified potential Vrm is used to calculate the pH. The outputs Voi1 and Voi2 of a first element and a second element located near one another in a sensor array are represented as follows. Voi1=Si1×pHi1+Gi1×Vrm+Ci1, Voi2=Si2×pHi2+Gi2×Vrm+Ci2. Voi is the output of the element, Si and Gi are sensitivity coefficients, and Ci is a constant, these values having been derived in advance. Here, where the potential Vrm is constant, and the elements located near one another are presumed to be at equal pH (pHi1=pHi2), the potential Vrm is identified by solving a linear equation with two unknowns.

摘要： Methods of maintaining accuracy in the measurement of one or more parameters of industrial water in industrial water systems are provided. The methods include the use of physical and/or chemical procedures to prevent and/or remove deposition from one or more surfaces utilized in measurement of the one or more parameters. The deposition may be caused by, for example, corrosion, fouling, or microbiological growth.

摘要： A reference electrode according to the present invention maintains continuity between an internal solution and measurement sample and measures the electrical potential of the measurement sample even if the measurement sample in a liquid junction of the reference electrode has air bubbles mixed therein. This reference electrode is provided with: a second body provided with a second internal solution chamber in which a second internal solution is housed and a liquid junction portion disposed in the second internal solution chamber such that the second internal solution and measurement sample that is to be measured come into contact; and an internal electrode disposed inside the second internal solution. The liquid junction portion is formed from a conduction component formed from a porous or fibrous component and an aperture adjacent to the conduction component.

摘要： A measuring arrangement for registering an analyte concentration in a measured medium includes a three electrode arrangement having a working electrode, a reference electrode and a counter electrode. The working electrode includes an analyte-insensitive, redox mediator, and the reference electrode a pH-sensitive electrode. The counter electrode can be formed of an inert, electrically conductive material. The measuring arrangement can be embodied to provide a desired voltage between the working electrode and the reference electrode and to register the electrical current flowing, in such case, through the measured medium, between the counter electrode and the working electrode.
