  • Device for determining the ozone concentration in air
    Patent number: 5923037
    Abstract: In a device for determining the ozone concentration by utilizing the surface chemiluminescence effect having a fan (13), a chemiluminescence element (8), a photomultiplier (6), a temperature sensor (16), and control electronics (12), an airflow generated by a fan (13) passes via a suction pipe (7) and an adjoining light trap system (17) through a venturi-shaped channel structure (2) along a metal block (9) in which a temperature sensor (16) is housed. The device is calibrated with respect to the temperature dependence of the reaction of a chemiluminescence disc (8) attached to the bottom of the metal block by determining the output voltage of a photomultiplier (6) in dependence on the temperature at a predetermined ozone concentration in the measured air.
