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 x pHi1 + Gi1 x Vrm + Cil, Voi2 = Si2 x pHi2 + Gi2 x 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 (pHil = pHi2), the potential Vrm is identified by solving a linear equation with two unknowns.

摘要翻译：本发明的目的是在pH传感器阵列中以高精度测量样品的pH，而不使用玻璃参比电极。每次测量样品时，识别样品的电位Vrm，并使用识别的电位Vrm来计算pH值。传感器阵列中彼此靠近的第一元件和第二元件的输出Vo1和Voi2如下所示。 Voi1 = Si1×pHi1 + Gi1×Vrm + Cil，Voi2 = Si2×pHi2 + Gi2×Vrm + Ci2。 Voi是元素的输出，Si和Gi是灵敏度系数，Ci是常数，这些值是事先得出的。这里，在电位Vrm恒定的情况下，假定彼此相邻的元素处于相同的pH（pHil = pHi2）时，通过求解具有两个未知数的线性方程来识别电位Vrm。

摘要： When the water content is determined, the electric conductivity has an effect on the water content. On the other hand, when the electric conductivity is determined, the water content has an effect on the electric conductivity. Accordingly, even if each characteristic is measured independently, each obtained value includes the error.
Contacting a pair of electrodes with soil, applying an alternate current input electric signal to one of the pair of electrodes, comparing a phase of an output electric signal from the other of the pair electrodes with a phase of the input electric signal; and determining the concentration of the ionic solute included in the solvent according to a difference of the phases. The difference of the phases is not dependent on the water content. An electrical conductivity is proportional to a water content and ion concentration, thereby, the water content of soil is available according to the measured electrical conductivity, while determining the ion concentration.
