ABSTRACT:
A method for checking and/or controlling a metallization process in a galvanizing or chemical is based on the measurement of light scattered off or reflected from a surface portion being metallized. A deviation from a predetermined nominal value of the scattered or reflected light intensity serves for controlling at least one process parameter to neutralize the deviation.
