Abstract
An electrical heating evaporator for evaporating active substances such as perfumes and/or insecticides, in which the evaporation rate regulator includes an electrical heater resistor for which the power supplied is regulated through a potentiometer constructed on a printed circuit board. The evaporation rate can be adjusted for a wide variety of types of chemical substances, without the need of substantially modifying the design of the device.
