Full-Spectrum Xenon Arc Exposure in a Benchtop Format
The DERUI benchtop xenon arc weathering tester is intended for laboratories that need controlled lightfastness, photostability and accelerated material-aging tests without the footprint and utilities of a large industrial chamber. Configure the optical filter, irradiance control and temperature functions around the actual material method—not a generic “sunlight simulation” claim.
When Is a Desktop Xenon Tester the Right Choice?
A compact xenon tester works best when the priority is repeatable comparison of small specimens, easy access and lower facility demand. It is commonly selected for formulation screening, incoming inspection and routine quality checks where a large specimen capacity or complex multi-factor climate cycle is not required.
Material Development
Compare formulations, pigments, stabilizers, coatings and adhesives under the same controlled exposure before committing to long outdoor trials.
Lightfastness and Color Change
Track color difference, fading, yellowing and gloss retention in textiles, plastics, inks, leather and interior materials.
Routine Quality Control
Use a defined exposure and reference material to identify batch-to-batch changes in durability and photostability.
Light, Temperature and Moisture Must Match the End Use
Filtered Xenon Light
A xenon arc lamp produces UV, visible and infrared radiation. Optical filters shape the spectrum for outdoor daylight, sunlight through window glass or another method-defined exposure.
Specimen Temperature
A black-panel or black-standard sensor represents the temperature reached by a dark exposed surface. It is not interchangeable with chamber-air temperature.

- If moisture is fitted, maintain nozzles, water quality, tanks and drains.
- Document maintenance and any exposure interruption in the test record.
Do Not Promise an Outdoor-Time Conversion
There is no universal statement such as “500 chamber hours equals one outdoor year.” Acceleration depends on material, climate, spectrum, irradiance, temperature, wetness and the property being measured. Establish correlation with outdoor exposure or a validated internal method.
Benchtop Xenon Arc Weathering Tester FAQs
What is a benchtop xenon arc weathering tester used for?
It exposes small material specimens to filtered xenon light and controlled temperature, with optional moisture functions, to compare fading, yellowing, cracking, gloss loss and other durability changes.
Is “desktop xenon lamp aging chamber” the same product?
Yes, the phrases are often used for the same compact instrument. “Benchtop xenon arc weathering tester” is the clearer technical and search-friendly product name.
Can this tester run ASTM G155 or ISO 4892-2?
Only if the offered configuration can reproduce every required condition of the selected procedure, including filter spectrum, irradiance, temperature and moisture. Send DERUI the exact method and edition for confirmation.
What is the difference between 340 nm and 420 nm irradiance control?
340 nm is commonly associated with short-wave UV damage in outdoor materials. A 420 nm control point is often selected for colorants and materials exposed through window glass. Follow the material method rather than choosing by preference.
Can it test three-dimensional products?
That depends on tray dimensions, lamp-to-specimen geometry and maximum specimen height. Provide the part drawing and exposed surface so DERUI can verify fit and irradiance uniformity.
Does the desktop chamber include water spray and humidity?
The supplied source does not confirm these functions. Treat them as configuration-dependent until the approved specification lists them.
How many specimens can be tested at one time?
Capacity depends on holder size, specimen dimensions, spacing and required exposure uniformity. Confirm the usable exposure area rather than relying only on the outside dimensions.
What information should I send for selection?
Provide the standard and edition, material, specimen size and quantity, filter, irradiance band, temperatures, moisture cycle, exposure duration, required evaluation and available utilities.
Confirm the Compact Xenon Configuration Before Ordering
Send DERUI your test standard, material, specimen dimensions, required filter, irradiance band, temperature and moisture cycle. We will verify the suitable benchtop configuration and identify any option needed for the procedure.
