BETA+ Light Exposure and Weathering Testing Instrument Experience. The Atlas Difference.

Accelerated Weathering with the Xenotest ® Beta+ The stability of materials to the stresses of weather is critical to the success of your products. Daylight exposure with heat and humidity exert permanent stresses on materials that affect overall appearance and other physical properties. The Xenotest Beta+ simulates and accelerates the natural weathering process providing reliable results concerning the long-term behavior of materials. By incorporating a variety of optional features, the Xenotest Beta+ can meet virtually all global weathering and lightfastness test requirements. Standards AATCC...

Features and Benefits The large, color touch screen makes operation easy and user friendly Non-ageing XENOCHROME ® filter systems decrease the cost of operation while increasing the precision of the test Simultaneous, automatic control of chamber temperature and black standard temperature as well as humidity closely simulates your material’s end-use temperature conditions test after test XENOSENSIV ® sensor combines accurate control of irradiance and black standard temperature to mirror on-rack exposure conditions (irradiance and black standard temperature are calibrated according to DIN EN ISO...

Equipment Technology The Technology in the Xenotest ® Beta+ q Versatile Instrument Functions – Electrical heating system achieves high temperature values even during dark cycles – Adjustable blower speed allows for simultaneous control of chamber temperature and black standard temperature Xenotest Beta+ touch screen with serial interface port q Ease of Operation with the Touch Screen – The large color touch screen not only shows you the current status of your test, but also provides a graphic display of the progression of your test parameters – The memory card interface loads data (e.g. software...

The Filtered Xenon Radiation in the Xenotest ® Beta+ XENOCHROME 300 or 320 with ten filters of special coated quartz glass simulates the solar radiation as specified in CIE publication No. 85, Table 4, or behind window glass, according to test requirements in the paint and plastics industries. UV and visible light wavelengths pass XENOCHROME filters while IR radiation is reflected and absorbed by three black absorbers. Heat is dissipated by air passing along the xenon lamp and over black absorber panels in the optical filter system. This prevents any unwanted temperature increase. Spectrum Comparison:...

Temperature Regulation in the Xenotest ® Beta+ The Xenotest Beta+ offers the choice of controlling test chamber temperature (CHT) or Black Standard Temperature (BST), or both simultaneously. The lower range of the test chamber temperature depends on the ambient air temperature in the laboratory: by increasing the lab temperature, the temperature in the test chamber increases accordingly. The black standard temperature is determined by the test chamber temperature and humidity. It is also influenced by the airflow rate, the irradiance and the installed filter system. By varying the blower speed...
