Abstract
A technique for continuously indicating the concentration of ozone dissolved in water, use being made of an amperometric cell, preferably formed of a gold cathode concentrically disposed within a tubular copper anode to define an annular passage, the cathode being rotated at high speed. A sample stream of the water is directed through the passage at a predetermined flow rate whereby in the absence of dissolved ozone, the cathode is polarized, but in the presence thereof, depolarization takes place to cause a current to flow in the cell, the current being measured to provide a reliable and continuous reading of ozone concentration.
