The SOLARBOX Models 522/1500, 522/1500e, 522/3000 and 522/3000e light exposure testers, are state-of-the-art light-exposure and weathering devices that can be used to create realistic conditions similar to natural outdoor weathering. Outdoor weathering is a decisive step for your product as it is moves forward from the laboratory to the final product. Intense solar radiation and an extreme greenhouse climate put coatings under considerable strain. Artificial exposure in the laboratory delivers fast, reproducible results. This can be repeated as often as required and can be performed completely independent of the actual weather and season.
