A B S T R A C T This invention relates to an apparatus and a method for determin- ing the concentration of a first reactant in a medium. A disc is saturated with a solution containing the first reactant and immersed into a second reactant fluid. A chemical reaction occurs between the first and second reactants to produce a gas which is trapped by the disc. The disc is buoyed to the surface of the second reactant fluid by the gas produced. The pro- cess is electronically timed using photocells to start and stop an electronic clock and a digital display displays the time elapsed in tenths of seconds.
