Abstract
Weathering apparatus with UV radiation sources and radiation sensors containing a double-calibrated UV sensor A weathering apparatus has one or more UV radiation sources () and one or more first sensors (), which are calibrated for a first spectral sensitivity range. In a first aspect of the invention, the sensor or one of the first sensors () is calibrated in such a way that the radiation power of a spectral range which is located within the first spectral sensitivity range can be determined from its output signal. In a second aspect of the invention, a second sensor () is provided, which is calibrated for a second spectral sensitivity range.
