Apparatus for increasing the humidity of outdoor weather

摘要

The assembly to increase the humidity of artificial weather conditions created in a test zone (1), for testing samples for weather resistance, has a graduated control unit (2) to set the air humidity level. A meter (4) registers the humidity level of the moistened air according to the time of a test duration, linked to a control unit (9). The control has vanes (8) to divide the test zone and dripping surfaces (7). Water with a salt content is used to humidify the air. The air humidity level is shown on a display (10) during the test period.
