発明の名称 (英語) ION CONCENTRATION MEASURING DEVICE AND ION CONCENTRATION MEASURING METHOD NEW
発明の概要(英語) An ion concentration measuring device 1 suppresses the effects of noise, and measures directly the concentration of ions contained in an object being measured. More specifically, the ion concentration measuring device 1 obtains the concentration of potassium ions 102 present in an object being measured 100. The ion concentration measuring device 1 is provided with: a first electrode portion 2; a sensor portion 3 which generates a current corresponding to a voltage provided to a voltage generating portion 6 and to the object being measured 100; and a control portion 8 which obtains the concentration of the potassium ions 102 on the basis of the current output from the sensor portion 3. The control portion 8 includes: a current value acquiring portion 17 which obtains a first current value (C1) generated by the sensor portion 3 when a positive voltage is provided, and which obtains a second current value (C2) generated by the sensor portion 3 when a negative voltage is provided; a difference acquiring portion 18 which obtains a difference (∆C) between the first current value (C1) and the second current value (C2); and a concentration acquiring portion 19 which obtains an ion concentration (T) on the basis of the difference (ΔC).
