Abstract:
1. A liquid property detection device comprising: a first electrode that is in a liquid container and is formed by a first metal having a first ionization tendency; a second electrode that is in the liquid container and is formed by a second metal having a second ionization tendency which is different from the first ionization tendency; an electromotive force obtaining unit configured to obtain an electromotive force which is generated between the first electrode and the second electrode in the liquid container, and the liquid container containing a liquid so that the liquid is in contact with the first electrode and the second electrode; a storage unit configured to store a table showing correspondence between a property of the liquid contained in the liquid container and the electromotive force; a property determination unit configured to determine the property of the liquid contained in the liquid container on the basis of the electromotive force obtained by the electromotive force obtaining unit and the table stored in the storage unit; and an output unit configured to output information corresponding to the property determined by the property determination unit.
