Water reforming effect determination device and water reforming effect determination method

摘要

PROBLEM TO BE SOLVED: To provide a water modification effect determination device and a water modification effect determination method, capable of easily determining that a water quality is kept modified.SOLUTION: There is provided a water modification effect determination device that includes: a first corrosion sensor having a stainless steel cathode and an iron anode, and being immersed in water before treatment which is to be supplied to a water treatment device; a second corrosion sensor having a stainless steel cathode and an iron anode, and being immersed in water after treatment which is discharged from the water treatment device; comparison means for comparing a current value A outputted from the first corrosion sensor and a current value B outputted from the second corrosion sensor; and determination means for discriminating a fact that a period is kept in which the current value A is larger than the current value B and determining that the water modification effect is maintained. Further there is provided a water modification effect determination method, which determines that the water modification effect is maintained, by discriminating the fact that the period is kept in which the current value A is larger than the current value B.
