MEASURING AND CONTROLLING THE MOISTURE CONTENT OF HAIR

Mean values of the humidity of air in a return air duct of a drying hood are formed at equal measurement intervals by means of a differential measurement process in a measurement . A first stop signal is transmitted from the measuring device to a hair drying programme device when a predetermined dif...

Zusammenfassung:Mean values of the humidity of air in a return air duct of a drying hood are formed at equal measurement intervals by means of a differential measurement process in a measurement . A first stop signal is transmitted from the measuring device to a hair drying programme device when a predetermined differential value of the measured air humidity mean values is not achieved.
