Atlas XENOTEST BETA + Xenon Arc Weathering Testing System. The Xenotest Beta+ is a premium stand-alone rotating rack xenon instrument with 4000cm2 exposure area. It comes with a complete set of parameter controls. Irradiance and temperature are measured and controlled directly on the sample level using on-rack XENOSENSIV sensor technology. The Beta+ complies with the vast majority of industry standards. Due to its large test chamber and highly reliable performance, it‘s ideal for larger capacities or sample sizes.           400 Volts, 3Phase, 50/60 Hertz 3x 2200 W air-cooled Xenon Lamps 4000 cm2 exposure area High-irradiance testing up to 120 W/m2 (2 Sun) Touch screen with colour display to monitor and display test parameters Direct Setting and Control of Irradiance (300-400 nm) Direct Setting and Control of Black Standard Temperature Direct Setting and Control of Chamber Temperature Direct Setting and Control of Relative Humidity Display of Diagnostic Messages Storage for 10 user-defined test methods Pre-programmed international standard test methods Multilingual User Interface Non-aging XENOCHROME filters to simulate outdoor daylight, daylight behind window On-rack XENOSENSIV 300-400 nm for measuring and controlling irradiance (in W/m2) and BST (°C) on sample level Selectable temperature control either by Chamber Temperature (max. 70 °C) or by Dual Control: Chamber Temperature and Black Standard Temperature (up to 130 °C) Fan-controlled temperature difference between Chamber and Black Standard Temperature Ultrasonic humidification system for humidity control Specimen spray system with integrated 60 l water reservoir
