Abstract
An apparatus for measuring ozone concentration in which ozone contained in a liquid to be measured is caused to shift into a clean gas in a gas-liquid contacting tube. The gas into which the ozone has shifted is supplied to a photocell into which light is projected. The gas supplied to the photocell is exhausted through an ozone dissolving tube. The light transmitted through the photocell enters a detector. The output from the detector is utilized as an indication of the concentration of ozone in the exhausted gas, and hence in the liquid.
