High strength. 5The purpose of the mechanical humidity controller MFR012 is to control the electric heating so that the dew point raises the relative humidity by more than 65% at a crucial time. In this way, condensation and corrosion are effectively prevented.1 x Humidity ControllerPlease note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
