SUGA GX25 Xenon Lamp Weathering Tester

The SUGA GX25 Xenon Lamp Weathering Tester is a compact yet powerful environmental simulation instrument specifically engineered to evaluate the lightfastness and weather resistance of daily commodities, packaging, and high-tech components. By utilizing a 2.5kW water-cooled xenon arc lamp, this tester provides a stable and accurate reproduction of the solar spectrum, allowing you to observe the degradation of materials caused by sunlight, heat, and humidity. It is an essential tool for manufacturers looking to predict product lifespan and maintain color stability in diverse consumer and industrial markets.

Features

Stable Water-Cooled Source: The 2.5kW water-cooled system manages the thermal load of the xenon lamp more efficiently than air-cooled alternatives, providing superior spectral stability and longer lamp life.

High-Temperature Capability: You can achieve a Black Panel Temperature (BPT) of up to $110^{\circ}\text{C}$, allowing for the simulation of extreme heat conditions found in automotive interiors or tropical outdoor environments.

Large Throughput for Compact Size: Despite its manageable footprint, the GX25 can accommodate up to 108 specimens simultaneously, making it ideal for high-volume batch testing.

Precise Dark Cycle Simulation: The system allows you to transition to a high-humidity dark mode ($95\%\text{ RH}$), effectively simulating nighttime dew and moisture absorption.

Customizable Spectrum: By utilizing specific filter combinations like the #295 outer filter, you can tailor the UV cutoff to match specific outdoor or indoor sunlight conditions.

Accessories

Xenon Burner: Replacement 2.5kW water-cooled xenon arc lamp.

Filter Sets: Various inner and outer filters (e.g., #295. #320. Quartz) for spectral adjustment.

Specimen Holders: Stainless steel clips designed for standard $65 \times 55\text{ mm}$ samples.

Black Panel Thermometer (BPT): Integrated sensor for accurate surface temperature monitoring.

Cooling Water Unit: Deionizer and heat exchanger system for lamp cooling.

Test Procedures

1. Sample Mounting

Secure your specimens into the stainless steel holders. Ensure the surface of the material is flush with the holder frame to guarantee uniform irradiance across the sample face.

2. Loading the Chamber

Place the holders onto the rotating specimen rack. Distribute them evenly to maintain the mechanical balance of the drum and ensure consistent airflow during the test.

3. Program Setting

Input your test parameters via the control panel. Define the irradiance level (e.g., $42\text{ W/m}^2$), the BPT for the light cycle, and the duration for both irradiation and dark phases.

4. Initiating Operation

Confirm that the cooling water is flowing and the filters are clean. Start the test. The specimen drum will rotate around the central xenon lamp, providing equal exposure to all 108 samples.

5. Assessment

Once the pre-set exposure time or radiant dose is reached, the system will automatically shut down. Remove the samples and compare them against a control specimen or a standard gray scale to evaluate color change.
