Q-SUN XE-2 Xenon arc chamber

The versatile Q-SUN Xe-2 tester is the simplest, most reliable, and easiest-to-use rotating rack xenon arc tester available.

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, and Vietnamese

◆ 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‑2 tester can subject test specimens to the equivalent of noon summer sunlight for 24 hours a day, every day.  This can highly accelerate the rate of product degradation and shorten test times.

Affordable

The Q‑SUN Xe‑2 tester’s low purchase price, low lamp prices, and low operating costs create an attractive price-to-performance ratio.

Configurations

● Q-SUN Xe-2-HE: full-spectrum sunlight, rotating rack specimen holder, humidity control, dual touchscreen displays

● Q-SUN Xe-2-HBSE: full-spectrum sunlight, rotating rack specimen holder, humidity control and water spray (front and back), dual touchscreen displays

Full-Spectrum Xenon Lamps

Xenon arc lamps provide 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.  Xenon lamps last for 3000 hours at normal irradiance and 1000 hours at high irradiance. The Q-SUN Xe-2 uses one lamp per machine. 

Optical Filters

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. The performance of Q-Lab's filters does 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-2 models use one optical filter lantern per machine. 

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 temperature can be set at any point between 35 °C and 105 °C, depending upon whether the black panel sensor is insulated or uninsulated, as well as irradiance level, filter type, lamp age and ambient room temperature.  

High Specimen Capacity

The Q-SUN Xe-2 tester has a large specimen capacity, supporting 31 specimens of 45 × 132 mm (1.8 × 5.2 in) each.  Its vertically-mounted specimen holders are very easy to install and remove.  

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 340 nm, 420 nm, or TUV (Total UV, 300-400 nm).  See the Q-SUN Brochure for more information.

Humidity Control

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 Q-SUN Specification Bulletin for details.

Optional Water Spray (Xe-2-HSE and Xe-2-HSBE)

Outdoor moisture attack is simulated via 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 Xe-2 with water spray.  

Optional Back Spray (Xe-2-HBSE)

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. 

Software & Operations

The Q-SUN Xe-2 tester’s displays are designed to be both functional and easy-to-use. Q-SUN testers feature dual, full-color touchscreen displays and can be programmed in 17 user-selectable languages (English, French, Spanish, Italian, German, Chinese, Korean, Japanese, Czech, Dutch, Polish, Portuguese, Russian, Swedish, Thai, Turkish, and Vietnamese). This system includes complete self-diagnostic error checking, constantly monitoring the status and performance of all systems. It also displays tester error messages and routine service reminders as needed. The multicolor LED status indicator light updates users on the tester’s operational state at a glance.
