The Weather-Ometer brings weathering conditions right into your laboratory. A few weeks testing with controlable cycles of light, water spray, and selected temperature and humidity equals years of actual outdoor exposure. The Weather-Ometer is safe to operate automatically 24 hours a day without attention. Used all over the world — Atlas Weather-Ometers, Launder-Ometers, and Fade-Ometers.
