Abstract

A device and method for the contactless and therefore non-destructive measurement of a degree of dryness of a coat of paint applied to a substrate. The device comprises at least one transmitter for electromagnetic radiation, at least one receiver for determining the absorption of the electromagnetic radiation radiated into the coat of paint, and a measuring means. In the measuring means, the raw measured values measured by the receiver are processed and the degree of dryness, calculated therefrom, of the coat of paint is displayed. Either microwave radiation or infrared radiation in the near infrared range is used as measuring radiation, at least one time-dependent measurement of the absorption at a constant wavelength being made in both cases. In addition, the invention relates to a method for determining the degree of dryness of a coat of paint by means of the device.
