摘要： A calibration liquid (1) is used for calibrating a water quality measurement device (100). The water quality measurement device (100) includes a plurality of sensors to be brought into contact with a measurement target liquid so as to measure concentrations of a plurality of types of target components contained in the measurement target liquid, and measures the concentrations of the plurality of types of target components. The calibration liquid (1) includes a solution which contains the plurality of types of target components at respective concentrations determined for the target components, and the solution has a pH within a predetermined pH range.
