weisstechnik® rain chambers are used in the development process, for quality assurance, and in end-of-line operations. They check for leaks on complete vehicles under repeatable conditions, varying from drizzle to heavy rain. The leak testing can be performed with vehicles at different tilt angles and with different types of rain. Leak testing systems are often used in manufacturing as 100 % tests and are similar to classic car washes. After passing through it, the vehicle is checked for leaks with a visual inspection and with the help of sensors and other test equipment.
