摘要

The device has an operating unit (1) for process control and for dosing fluids and gases and provided with pumps and controller. A separate mixing unit (2) is provided for mixing the fluids and gases. The mixing unit is directly screwed to an outer wall of a container e.g. test chamber, to be air-conditioned. An air-permeable fleece material is immersed with fluid to be evaporated in the mixing unit. A gas to be humidified is blown by the fleece material. Partial vapor pressure of a gas mixture is adjusted by introduction of dry gas into a mixing chamber.
