PROBLEM TO BE SOLVED: To provide a measuring apparatus capable of easily grasping the state of calibration etc. and correctly determining an end point of calibration etc. without especially having to require empirical knowledge. SOLUTION: The measuring apparatus 1 computes an operation value to a detection value acquired from a detection part 2, selects one from among a plurality of display modes on the basis of the operation value, displays it by flashing or lighting it up. The measuring apparatus 1 changes the period and/or duty ratio of the flashing according to the operation value. The operation value is preferably the amount of change between a detection value at some point of time and a detection value at a prior point of time, and the detection part 2 is preferably an ion electrode.
