the sun you have always wanted: sunshine day and night for accelerated light stability and weathering tests.
radiant energy in the solarbox is provided by a single superior air-cooled xenon lamp generating an irradiance level up to two times the sun one. Irradiance is the rate at which light energy falls onto the samples. A weathering tester must control irradiance if it is to achieve accurate and reproducible test results. Solarbox offers constant measurement and control of irradiance during every test, compensating for lamp and uv filter ageing via a closed loop irradiance narrow-band sensor control system. Irradiation uniformity is guaranteed by a parabolic reflector chamber with the xenon lamp in the focus, the best design for a reliable flat-bed xenon exposure system and very good agreement with rotating drum xenon exposures.
temperature controltemperature is another component of the end use environment which plays a key role in material degradation. Heat in the natural environment comes from the infrared portion of natural sunlight. An object exposed to direct sunlight is always warmer than the air surrounding it. Your product is exposed in the same manner in our solarbox tester.
the radiant heat received from the xenon lamp is continuously monitored and controlled by a b.s.t. (black standard thermometer) built in the plane of test panels near your samples. In solarbox 1500e and 3000e there is the control and display of the black standard temperature between 35c and 100c. The importance of temperature in the weathering degradation process is that the kineticreaction rate doubles for every 10c temperature increase. Consequently, because the temperature produces an accelerated ageing, it is essential to be able to control of b.s.t. During exposure to filtered xenon radiation.
simulating the effect of rain and moisture
a flooding system for conducting weathering tests with freely selectable flooding interval is an available option for solarbox 1500e and 3000e:water level indicatorcontinuous flooding possibleflooding intervals selectable between 1 and 999 minutes throughout the test programwater temperature of 30c to 50c.
during flooding, the xenon lamp can be programmed on or off. The flooding system operates with demineralised water from a closed recycling circuit so to minimize the need of demineralised water but offering the same test results of a high consumption spray system. Pvc and corrosion-resistant materials ensure long life of this tank pump system: capacity up to 50 litres.
xenon lamp and uv filters combination optimize sunlight simulation
the solarbox1500-1500eand solarbox3000-3000eare 4 ultimate filtered xenon light exposure and weathering instruments which simulate realistic natural outdoor weathering conditions.
the large dimensions of solarbox 3000 and 3000e test chamber can accommodate 3 dimensional objects and finished industry products.
accelerating the process requires the accurate reproduction of the suns rays.the air cooled xenon lamp in the solarbox replicates the total spectrum of the sun and not just the short wavelength uv, as we have using uva or uvb fluorescent lamps.
easily interchangeable light filters allow the reproduction of the specific spectral distributions found in your products end-use environments.
