The New Standard in Rotating Rack Xenon Testers
The Q-SUN Xe-2 rotating rack xenon arc chamber is a full featured weathering and lightfastness chamber at a breakthrough price. The Q-SUN Xe-2 tester’s xenon arc lamp provides the best match to full spectrum sunlight. A variety of optical filters are available to match nearly any global xenon test standard. Simultaneous, precise control of relative humidity, chamber air and black panel/black standard temperature is standard. Optional water spray can be added to simulate the erosion effects of rain.
Easy To Use
The Q-SUN Xe-2 xenon test chamber is easy to install, easy to use and easy to maintain. Specimen mounting and evaluations are simplified with specially designed specimen holders. The Xe-2 tester is completely automated and can operate continuously, 24 hours per day, 7 days per week. Other features include:
A product exposed outdoors to direct sunlight experiences maximum light intensity for only a few hours each day. The Q-SUN Xe-2 tester can accelerate results by subjecting test specimens to the equivalent of noon summer sunlight for 24 hours a day, every day. Consequently, specimen degradation can be highly accelerated.
The Q-SUN Xe-2 tester was specifically designed to be an affordable rotating rack xenon tester. Its low purchase price, low lamp price, and low operating costs set a new standard for lightfastness testing. Now even the smallest lab can afford rotating rack xenon arc weathering and lightstability testing.

Full Spectrum Xenon Lamps
Xenon arc lamps give the best reproduction of the full-spectrum of natural sunlight. Q-Lab’s lamps are air-cooled (vs. water-cooled), which makes them more economical, highly efficient and very low maintenance. Lamps last for 1500 hours and the Q-SUN Xe-2 tester uses a single 1800W lamp per machine.
The Q-SUN Xe-2 model’s optical filter lanterns are designed to produce the spectra specified in many global weathering and lightfastness test standards. These standards apply to a variety of industries for outdoor applications, as well as interior applications where sunlight may enter through a window. The lanterns consist of an outer borosilicate or quartz glass cylinder and two sets of 7 inner filters, arranged in a two-tier heptagon.
Temperature Monitoring & Control
Control of temperature is important because it influences the rate of degradation. Specimen exposure temperature is precisely controlled in the Q-SUN Xe-2 tester using black panel and chamber air temperature sensors. The black panel temperature can be set at any point between 35ºC and 105ºC, depending upon whether the black panel is insulated or uninsulated, irradiance level, filter type, lamp age, chamber air temperature and ambient room temperature. See LX-5046 – Q-SUN Specification Bulletin.
Large Specimen Capacity
The Q-SUN Xe-2 tester has a large specimen capacity, supporting 31 specimens of 46 mm x 122 mm each. Its vertically mounted specimen holders are very easy to install and remove. See our specimen mounting page or Accessories Tab for more information.
SOLAR EYE Irradiance Control
The SOLAR EYE Irradiance Control System constantly monitors and controls lamp output to assure precise light exposure and to maximize repeatability and reproducibility of test results. Irradiance control is available at 340nm or 300-400nm TUV (Total UV). See LX-5046 – Q-SUN Specification Bulletin.
Relative humidity (RH) control is standard in the Q-SUN Xe-2 tester. It allows the user to simultaneously control and display RH, black panel temperature, and chamber air temperature. Note that purified water is required for proper operation of the RH system in the Xe-2 tester. See LX-5046 – Q-SUN Specification Bulletin.
Optional Water Spray
Outdoor moisture attack is simulated via an optional pure water spray in the Xe-2 tester. A spray nozzle located in the top of the chamber can be programmed to operate during either the dark or light cycle. Note that purified water is required for proper operation of the water spray and RH features in the Xe-2 tester. See LX-5046 – Q-SUN Specification Bulletin.
Optional Back Spray (Model Xe-2-BS)
Back spray is available for the Xe-2 tester and is required by some SAE test methods; it allows water to be sprayed on both the front and back of specimens simultaneously. Note that purified water is required for proper operation of the Xe-2 with back spray.
Controls & Optional Software
Designed to be both functional and easy to use, the Q-SUN Xe-2 controller can be programmed in five user-selectable languages (English, French, Spanish, Italian or German) and includes complete self-diagnostic error checking. The controller constantly monitors the status and performance of all systems. It also displays simple warning messages, routine service reminders or performs safety shutdown, as needed.
An external USB port on every Q-SUN Xe-2 tester allows users to perform software upgrades quickly to address key performance issues. For quality systems that require documented proof of test conditions, this USB port can also be used to download tester performance history. Additionally, every Q-SUN Xe-2 tester is equipped with an Ethernet connection. Optional VIRTUAL STRIPCHART PC software allows the user to automatically record and monitor exposure conditions and directly transfer data from the Q-SUN Xe-2 test chamber to a Windows-based computer. Data from either the USB export or PC application can be emailed directly to Q-Lab’s technical support desk for expert troubleshooting and diagnostics.
The Q-SUN Xe-2 tester’s xenon arc lamp produces the most realistic reproduction of full spectrum sunlight including ultraviolet, visible light and infrared radiation. For some materials, exposure to the full spectrum is necessary to provide an accurate simulation, especially when testing for color change and lightfastness in textiles.
Long Lasting Lamps
The Q-SUN Xe-2 uses a single, 1800W air-cooled xenon arc lamp. Air-cooling significantly reduces operating and maintenance expenses over water-cooled lamp devices. Lamp life is warranted to 1500 hours under normal operating conditions. See LX-5046 –Q-SUN Specification Bulletin.
Changing the Xe-2 lamp is quick and easy – it is easily accessible from the top of the tester. Replacement only requires the user to open an access door, release a set screw, and remove the trigger finger. The lamp and lamp housing can then be simply lifted out of the tester.
A Choice of Optical Filters to Simulate a Variety of Environments
Xenon light must be properly filtered to achieve the appropriate spectrum for each particular application. Differences in spectra may affect both the speed and the type of degradation. The Q-SUN Xe-2 tester’s optical lanterns consist of an outer borosilicate or quartz glass cylinder and two sets of 7 durable inner filters, arranged in a two-tier heptagon. They are designed to meet the spectral requirements of virtually all global xenon arc standards,including those published by ISO, ASTM, AATCC, and automotive OEMs. The Q-SUN Xe-2 can simulate direct sunlight or sunlight through window glass.
Easy Calibration Assures Accuracy
The Q-SUN Xe-2 black panel temperature sensor needs to be calibrated periodically by the user. This assures accurate and consistent results.
Calibrating the Xe-2 black panel temperature sensor is simple using the Universal Calibrator system’s UC202 calibrated temperature sensor and UC1 handheld display, or the historical CT202 calibration thermometer, and takes only a few minutes. Note that the CT202 and UC202 calibration thermometers come with either an uninsulated black panel (UC202/BP, CT202/BP) or insulated black panel (UC202/IBP, CT202/IBP) sensor. This sensor must match the type of sensor actually used in the Xe-2 tester. The low-cost, combination relative humidity/chamber air temperature is designed to be replaced once a year by the user and cannot be recalibrated.
Calibration of the UC202 and CT202 thermometers needs to be performed annually. The UC202 thermometers were designed to be disposable and cost-efficient, and should be replaced annually with a freshly-calibrated UC202. The CT202 thermometer needs to be returned to Q-Lab once per year for an inexpensive recalibration. UC202 units may also be returned for calibration for users who prefer recalibration to replacement. Our calibration labs are ISO 17025 accredited by the American Association of Laboratory Accreditation (A2LA – Ohio Certificate Number 2382-01, China Certificate Number 2383-02, and England Certificate Number 2383-03). Calibrations are traceable to the U.S. National Institute of Standards and Technology (NIST).
Easy Calibration Assures Accuracy
The Q-SUN Xe-2 SOLAR EYE irradiance sensor needs to be calibrated periodically by the user. This assures accurate and consistent results. Calibrating the Xe-2 tester is simple using the Universal Calibrator system’s UC20 calibration radiometer or the legacy CR20 calibration radiometer, and takes only a few minutes.
Both UC20 and CR20 devices come with a 340nm, 420nm, or 300-400nm TUV (Total UV) sensor and must match the type of sensor actually used in the Q-SUN tester. CR20 calibration radiometers must also match the optical filter in use in the Q-SUN.
Calibration of the UC20 and CR20 radiometers needs to be performed annually. The UC20 sensors were designed to be disposable and cost-efficient, and should be replaced annually with a freshly-calibrated UC20. The CR20 radiometer needs to be returned to Q-Lab once per year for an inexpensive recalibration. UC20 units may also be returned for calibration for users who prefer recalibration to replacement. See our Recalibration Return Procedure.
