Method for determining the amount of chlorine and bromine in water

摘要

A thick film electrochemical microsensor device for measuring or regulating chlorine and bromine in water, comprising a substrate to which is applied an optimum arrangement of at least two electrodes. The device is especially useful for measuring or regulating chlorine and bromine levels in swimming pool or spa water. A method of measuring or regulating ions of at least one of chlorine and bromine in water is also described, which comprises contacting the water with the microsensor of the present invention; measuring the current output of the microsensor; determining the level of at least one of chlorine and bromine indicated by the current output; and generating a signal.
