Abstract
Electronic apparatus for detecting the amount of a predetermined substance disposed in a fluid medium and method for its use, the apparatus comprising, in combination, first means for contacting said fluid medium and for detecting an electrical condition of said fluid medium caused at least in part by said predetermined substance to be detected; second means operatively and electrically connected to said first means for generating at least one signal that is substantially proportional to said quantity of said predetermined substance disposed in said fluid medium; and third means operatively and electrically connected to said second means for using said signal that is substantially proportional to said quantity of said predetermined substance disposed in said fluid medium.
