Weathering Testing Apparatus
The BANDOL WHEEL®H 532/II is the “wet/dry” version and is based on the conventional version of the device, with an additional immersion phase for the samples. For this purpose, a boiler was installed in the lower part of the test chamber. By regulating the fill-level of the solution liquid in this boiler, the ratio between dry and wet operations can be adjusted in a highly accurate, safe and reproducible manner. To complete the weathering cycle, an aperture can be installed in the device (for extending the lifespan of the lamp).
