Unit for establishing the conversion rate of an ozone conversion element, comprises air supply channels, a switching unit and an ozone sensor

摘要

The arrangement for determining the conversion rate of an ozone conversion element which has a catalyst coating comprises primary (1) and secondary (2) air supply channels, and a third air channel (4) connected to them via a switching unit. An ozone converter element has an associated sensor, and the switching unit directs air in front or behind the element to the sensor. The switching unit also controls the sensor.
