Xenotest 220 is a highly economic textile color lightfastness tester that can test up to 250 samples simultaneously. It complies to industry standards ISO 105- B02, AATCC TM16 (option 3), and Marks & Spencer C9, C9A. Within the Atlas Xenotest series, the Xenotest 220/220+ models are specifically designed for textile lightfastness testing, which meet common textile standards.

XenoCal Sensors for Accurate Instrument Calibration.

All XenoCal calibration sensors work independant of the instrument's control system to ensure proper calibration. The combined XenoCal 300-400 BST sensor measures the irradiance in the UV range of 300-400 nm and the (insulated) black standard temperature (BST) simultaneously. The XenoCal 420 sensor measures the irradiance at 420 nm and the XenoCal BPT sensor measures the (uninsulated) Black Panel Temperature. Only annual or semi-annual calibrations are typically required due to the sensor’s accurate calibration and long term stability.

Specimen Holders and Cover Masks:

Specimen holders with quick-clamp technology enable easy specimen preparation. Holders are available for specimens less than 3 mm, up to 10 mm thick, as well as appropriate cover masks for testing to various ISO and AATCC textile standards.



Humidity Control:

Because water is a precious resource, Xenotest humidifiers are optimized to reduce water consumption, necessary to meet test conditions. The extremely efficient ultrasonic humidifiers are linked to an integrated 60 liter water reservoir, enabling continuous operation over a period of 3 to 4 weeks*. Additionally, the humidifier's design allows the speed and direction of the air flow inside the test chamber to operate as efficiently as possible, providing the highest uniformity throughout the exposure area.

(*under the conditions of standard ISO 105-B02)

Temperature Control:

Ambient and surface temperatures can have a significant impact on degradation and fading rates. Xenotest chambers control BST directly on the specimen rack within ± 2°C. Both BST and CHT can be controlled simultaneously in all Xenotest instruments to achieve ideal test conditions (420 nm, BPT control option available).
