•Datasheet: 499AOZ Dissolved Ozone Sensor
The 499AOZ sensor is intended for the continuous determination of dissolved ozone. The primary application is ozonation basins in municipal water filter plants. Ozone is also used as a disinfectant in bottling and food processing plants.
The 499AOZ is a membrane-covered amperometric sensor. The sensor consists of a gas-permeable membrane stretched tightly over a gold cathode. A silver anode and an electrolyte solution complete the internal circuit. During operation, ozone diffuses from the sample through the membrane. Once inside the sensor, the ozone reacts with the electrolyte solution to form an intermediate compound. A polarizing voltage applied to the cathode completely reduces the intermediate. The reduction produces a current, which the analyzer measures. The current is directly proportional to the rate at which ozone diffuses through the membrane, which is ultimately proportional to the concentration of ozone in the sample.
- Rugged construction.
- Easily replaceable membrane; no special tools required.
- Automatic compensation for changes in membrane permeability with temperature.
- Automatic pressure equalization maintains correct membrane tension.
- Variopol connector option allows the sensor to be replaced without running new cable.
