Xenotest Alpha+ (discontinued)

  • Overview +


    The Xenotest Alpha+ has been discontinued and cannot be ordered any more. Please see its successor instruments Xenotest 220/440 and Ci3000 Weather-Ometer.


    The Xenotest Alpha+ is a compact stand-alone rotating rack xenon instrument with 1320 cm2 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 Alpha+ complies with the vast majority of industry standards setting the benchmark in narrow tolerance testing. Due to its highly reliable performance and high irradiance capabilities, it‘s often chosen by R&D departments or commercial Service Test Houses.
