Q-SUN Xe-2 จาก Q-LAB เครื่องจำลองแสงแดด (Light Fastness & Color Fading Tester)

Q-SUN XE-2 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:

      – Remarkably simple user interface in 17 user-selectable languages: 

                                 English, Spanish, French, German, Italian, Japanese, Chinese, Korean,

                                 Czech, Dutch, Polish, Portuguese, Russian, Swedish, Thai, Turkish, Vietnamese

       – Built-in Ethernet connection for data logging with provided software

       – Comprehensive self-diagnostic warnings and service reminders

– Quick and easy user-performed calibration with patented AUTO-CAL 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-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. 

Affordable
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 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.  Standard lamps last for 1500 hours and the Xe-1 uses one lamp per machine. Enhanced lamps last for 3000 hours at normal irradiance and 1000 hours at high irradiance.

Sunlight Simulation
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. 

Standard and “Plus” Lamps
Standard and “Plus” Lamps (Replacing Long Lasting Lamps)
The Q-SUN Xe-2 tester uses a single, air-cooled xenon arc lamp. It significantly reduces operating and maintenance expenses compared to water-cooled lamps. Typical lamp life for a standard

lamp is 1500 hours at normal irradiance. Plus lamps are available that allow for improved lamp life, as well as the ability to test at high irradiance. These lamps typically last for 3000 hours at

normal irradiance, and 1000 hours at high irradiance.  

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.  Three categories of filters are available to simulate a variety of service environments, which are shown below.  The application or test method dictates which filters should be used.  See LU-8054a – SPD for QUV, Q-SUN, and Noon Summer Sunlight.

Daylight Filters

Daylight filters are used to simulate direct, noon summer sunlight . They provide the best correlation to natural exposures for most applications.  Materials that are typically used outdoors (e.g. roofing and exterior coatings) should be tested using daylight filters.  Three different types of daylight filters are available for the Q-SUN Xe-1 tester:  Daylight – F, Daylight – Q and Daylight – B/B. Daylight-Q and Daylight-F filters meet the specifications of Type I Daylight filters described in ASTM and ISO standards. Daylight-B/B filters are classified as Type II Daylight filters.

Window Glass Filters

Window glass filters produce spectra equivalent to sunlight coming through window glass.  This spectrum can also simulate other indoor lighting such as the harsh lighting found in a typical commercial or office environment.  Window glass filters are used for indoor materials such as printing materials and textiles.  Four different window glass filters are available for the Q-SUN Xe-1 tester:  Window – Q, Window – B/SL, Window – SF-5 and Window – IR.

Extended UV Filters

Extended UV Filters allow excess UV, below the normal cut-on of natural sunlight.  They are used to produce faster or more severe test results.  Extended UV Filters are specified in some automotive test methods and are sometimes used for aerospace applications. The most common Q-SUN filter of this type is the Extended UV – Q/B.

The Q-SUN Xe-2 tester’s long-life filters are exceptionally durable and maintain the required spectrum indefinitely.  After many years of use, Q-SUN filters have yet to show any signs of aging. A Choice of Filter for Q-SUN  for a more detailed discussion of optical filters, but the information above can be a useful guide.
