Q-SUN XE-3 XENON TEST CHAMBER

The Q-SUN Xe-3 xenon arc chamber reproduces the damage caused by full-spectrum sunlight and rain. In a few days or weeks, the Q-SUN tester can reproduce the damage that occurs over months or years outdoors.

The Q-SUN Xe-3 tester is a full-featured lightfastness, colorfastness, and photostability chamber at a breakthrough price. It utilizes three separate xenon lamps for a large capacity. The Q-SUN Xe-3 tester’s slide out specimen tray is 451mm x 718mm and is useful for exposing large, three-dimensional parts or components. The Xe-3 tester offers standard humidity control, and optional spray, back spray and chiller features.

The Q-SUN Xe-3 is the only xenon arc tester that also has an optional dual spray capability. This allows for a second liquid such as acid rain or soap solutions, to be sprayed onto test specimens.

The Q-SUN Xe-3 is the simplest, most reliable, and easiest to use full-sized xenon arc chamber available.

Overview
A More Realistic Xenon
The Q-SUN Xe-3 tester’s xenon arc lamps provide the best match to the full spectrum of sunlight. Near-horizontal specimen mounting and optional water and back spray provide the most realistic moisture simulation available in a xenon arc tester. The Xe-3 tester also is the only xenon test chamber to offer a dual spray option, allowing a second liquid (such as acid rain) to be sprayed onto test specimens. An optional chiller for low temperature applications also allows for simultaneous control of both black panel and chamber air temperature.

Easy To Use
The Q-SUN Xe-3 xenon test chamber is easy to install (proper ventilation required). It is easy to use and practically maintenance-free. Specimen mounting and evaluation is fast and easy with the unique slide-out specimen tray. The Xe-3 tester is completely automated and can operate continuously, 24 hours per day, 7 days per week. Other features include:

• Remarkably simple user interface in five user-selectable languages: English, French, Spanish, Italian or German
• Built-in Ethernet connection for data logging
• Comprehensive self-diagnostic warnings and service reminders
• Quick and easy calibration with patented AUTOCAL system

Fast Results
A product exposed outdoors to direct sunlight experiences maximum light intensity for only a few hours each day. The Q-SUN Xe-3 chamber can subject test specimens to the equivalent of noon summer sunlight for 24 hours a day, every day. Consequently, specimen degradation can be highly accelerated.

Affordable
The Q-SUN Xe-3 tester’s low purchase price, low lamp prices and low operating costs create a breakthrough in the price/performance equation. Now even the smallest lab can afford xenon arc testing.

Features
Full Spectrum Xenon Lamps
Xenon arc lamps give the best reproduction of full spectrum natural sunlight. Q-Lab's lamps are air-cooled (not water-cooled), which makes them more economical, highly efficient and very low maintenance. Lamps last for 1500 hours and the Xe-3 uses three lamps per machine.

Optical Filters
A choice of optical filters is available to simulate a variety of service environments including direct sunlight and sunlight through window glass. The performance of Q-Lab's filters not decline with age; therefore, filters do not need to be replaced under normal operation. The only exception to this is the Window-IR filter, which requires regular replacement. All Q-SUN Xe-3 models use three optical filters per machine. See LX-5060 - A Choice of Filters for Q-SUN.

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-3 tester using a black panel temperature sensor. The temperature can be set at any point between 42ºC and 120ºC, depending upon: whether the sensor is insulated or uninsulated, irradiance level, filter type, lamp age and ambient room temperature. With an optional chiller, both black panel and chamber air temperature can be simultaneously controlled, giving the ultimate control of specimen temperature. See LX-5000 - Q-SUN Xe-1, Xe-2 & Xe-3 Brochure.

Versatile Specimen Mounting
The flat specimen mounting tray in the Xe-3 accommodates different shapes and sizes of specimens, including three-dimensional parts. A variety of specimen holders are available. The Xe-3 mounting tray is 451mm x 718mm and holds up to 55 specimens @ 51mm x 102mm each. See our specimen mounting page, LX-5080-SM - Q-SUN Xe-1 & Xe-3 Specimen Mounting or Accessories Tab for more information.

SOLAR EYE Irradiance Control
The SOLAR EYE irradiance control system constantly monitors and controls lamp output. This assures precise light exposure and maximizes reproducibility of test results. Irradiance control is available at 340nm, 420nm or TUV (Total UV). See LX-5000 - Q-SUN Xe-1, Xe-2 & Xe-3 Brochure.

Humidity Control
Relative humidity (RH) control is standard in the Q-SUN Xe-3 model. It allows the user to simultaneously control, monitor, and display RH, black panel temperature, and chamber air temperature. Note that purified water is required for proper operation of the Xe-3 with humidity control. See LX-5000 - Q-SUN Xe-1, Xe-2 & Xe-3 Brochure.

Optional Water Spray (Models Xe-3-HS, Xe-3-DS, Xe-3-BS, Xe-3-HSC)
Outdoor moisture attack is simulated via a pure water spray option in the Xe-3 tester. Two spray nozzles are located in the top of the chamber. Spray can be programmed to operate during either the dark or light cycle. Note that purified water is required for proper operation of the Xe-3 with water spray. See LX-5000 - Q-SUN Xe-1, Xe-2 & Xe-3 Brochure.

Optional Back Spray (Model Xe-3-BS)
Back spray is available for the Xe-3 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-3 with back spray.

Optional Dual Spray (Model Xe-3-DS)
Dual spray is available for the Xe-3 tester. It allows a second liquid solution, such as acid rain or soap solution, to be sprayed onto test specimens. A large external reservoir, centrifugal pump and filter are attached to a portable cart that sits next to the Xe-3 tester. See LX-5025a - Acid Etch for Auto.

Optional Chiller for Low Temperature Applications (Model Xe-3-HSC)
For some interior products such as pharmaceuticals and cosmetics, lower exposure temperatures are necessary to prevent unnatural degradation. An optional chiller is available for the Xe-3 tester to lower temperatures when testing such heat sensitive materials. See LX-5000 - Q-SUN Xe-1, Xe-2 & Xe-3 Brochure. With a chiller, a Q-SUN Xe-3 tester can operate at 31-120ºC and 50% RH, depending upon sensor type, irradiance level, filter type, lamp age, and ambient room temperature and humidity. The Xe-3 chiller is designed to stand alongside the full-sized Xe-3 tester, and is provided with wheels for easy repositioning.
Controls & Optional Software
Designed to be both functional and easy to use, the Q-SUN Xe-3 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.
For quality systems that require documented proof of test conditions, every Q-SUN Xe-3 tester is equipped with an Ethernet connection. Optional “Virtual Strip Chart” PC software allows the user to automatically record exposure conditions and directly transfer data from the Q-SUN tester to a Windows-based computer. This data can also be emailed directly to Q-Lab's technical support desk for expert troubleshooting and diagnostic
