MEASURING DEVICE AND MEASURING METHOD FOR MEASURING PHOTOCATALYTIC ACTIVITY OF A PHOTOCATALYTIC LAYER

摘要

The invention relates to a device and method for measuring photocatalytic activity of a photocatalytic layer irradiated by a source of radiation. The device contains a measuring probe (1) with a measuring head, the measuring head being equipped with an indicator (5) that reacts to the photocatalytic activity of the photocatalytic layer (3). The inventive method provides that an indicator (5), which reacts to the photocatalytic activity and which serves to measure the photocatalytic activity, is positioned at a short distance from the photocatalytic layer (3). The inventive device and method make it possible to measure photocatalytic layers in a non-destructive and defined manner.
