Abstract: To provide a technology that can suppress an operation unintended by a user caused by an erroneous operation by the user. An electrochemical sensor according to one aspect of the present invention is for measuring a concentration ratio between sodium ions and potassium ions in a liquid to be measured that includes: a sensor head; and a calculation unit that allows performing a calibration operation and a measurement operation. The calibration operation calculates a characteristic parameter of the sensor head based on sensing data of the sensor head in a state where the sensor head is brought into contact with a calibration agent. The measurement operation calculates the concentration ratio based on the characteristic parameter of the sensor head and the sensing data of the sensor head in a state where the sensor head is brought into contact with the liquid to be measured.

Abstract: The electrolyte analysis test strip of the present invention includes a substrate extending in one direction. A first ion-sensitive film provided in a specific region on the one end side in the one direction and a first extraction electrode extending from the first ion-sensitive film to the other end side are provided on one main surface of the substrate. A second ion-sensitive film provided in a specific region on the one end side and a second extraction electrode extending from the second ion-sensitive film to the other end side are provided on the other main surface of the substrate. The first ion-sensitive film and the second ion-sensitive film each come into contact with an electrolyte to generate a first potential corresponding to a concentration of a first ion species and a second potential corresponding to a concentration of a second ion species, respectively.

Abstract: The present invention provides an electrolyte analysis test strip for measuring a concentration of ions contained in an electrolyte. The electrolyte analysis test strip includes a substrate extending in one direction. An ion sensitive electrode is provided in specific regions on a side of one end in the one direction on a main surface of the substrate. A main extraction electrode extends from the ion sensitive electrode to a side of an other end. A solution detection electrode is provided in a proximal region in a manner separated from the main extraction electrode, and is for detecting whether or not the solution detection electrode is in contact with the electrolyte. An auxiliary extraction electrode extends from the solution detection electrode to the side of the other end in a manner separated from the main extraction electrode.

Abstract: An electrolyte analysis device includes a substrate extending in one direction, a main base portion provided on a main surface of the substrate, an ion selective film provided to be in contact with the main base portion so as to cover the main base portion, and an auxiliary base portion provided on the substrate. In a state where the electrolyte is in contact with a side of one end of the substrate so as to cover the side of the one end, a peeling determination unit obtains a potential of the main base portion and a potential of the auxiliary base portion, respectively. Whether or not the ion selective film is peeled from the main base portion is determined based on a potential difference between an obtained potential of the main base portion and an obtained potential of the auxiliary base portion.
