Abstract: A method for detecting the presence of humidity on a surface of a flat strip, in particular a bare metal strip or of a coated metal strip having the following steps: blowing on the surface an impinging air flow producing an air flow deflected by the surface, the impinging air flow not being saturated, measuring a humidity content of at least a portion of the deflected air flow, comparing the humidity content of the impinging air flow and the deflected air flow, if said humidity content of the deflected air flow is superior to the humidity content of the impinging air flow, the presence of humidity on the surface of the bare metal strip or of the coated metal strip is detected.
