A human load of regularly measuring a pH of a position 4 meters from a discharge point during a term of a commissioning of a ship with a scrubber apparatus is reduced. Provided is an apparatus provided inside a ship having a scrubber, including a first pH measuring instrument which measures a pH value of washing water discharged from the scrubber to outboard, a second pH measuring instrument which measures a pH value of washing water supplied from outboard to the scrubber, and a calculating unit which calculates a pH value of water at a predetermined position outboard, based on a dilution ratio which shows a ratio by which the washing water discharged to outboard is diluted at the predetermined position outboard, the pH value measured by the first pH measuring instrument, and the pH value measured by the second pH measuring instrument.
