MEASURING APPARATUS

PROBLEM TO BE SOLVED: To provide a measuring apparatus which allows a user to start calibration after confirming a state suitable for the calibration in spite of a property value of a standard liquid, and high reliability can be given to a result of the calibration.SOLUTION: A measuring apparatus comprises a detection unit 21 which has a pair of electrode sections and outputs a potential difference generated by bringing these electrode sections into contact with a measuring target, and a main body which displays a property value of the measuring target obtained based on the potential difference as a measurement result. The measuring apparatus further includes a calibration starting command receiving unit 6 which receives a calibration starting command from a user, a stability calculation unit 7 which calculates stability of the property value based on a variation of the property value, and a display output unit 8 which displays a value of the stability itself at least prior to receiving the calibration starting command from the user by the calibration starting command receiving unit 5.
