Applications:

SUGA SX75 7.5kW Super Xenon Weather Meter is designed to artificially replicate indoor and outdoor environments—such as sunlight, temperature, humidity, and rainfall—to accelerate the aging of products and materials, thereby predicting their service life.

This model delivers irradiation levels up to three times that of solar ultraviolet light (180W/m²), meeting the demands of today's rapidly evolving products.

Product Information:

The SUGA SX75 7.5kW Super Xenon Weather Meter is an advanced, ultra-accelerated aging system engineered to artificially reproduce extreme indoor and outdoor environments. By simulating the combined effects of solar radiation, temperature, humidity, and rainfall, this instrument allows you to predict the service life of materials with unprecedented speed. The SX75 distinguishes itself by delivering an irradiance of up to $180\text{W/m}^2$ (in the 300-400nm range)—triple the intensity of natural sunlight—meeting the rigorous testing demands of today's fast-paced product development cycles.

Features

Ultra-Accelerated Aging: You can achieve testing speeds up to three times faster than standard xenon testers, significantly reducing the R&D cycle for new materials.

7.5kW Water-Cooled Stability: The high-power water-cooled lamp ensures stable irradiance even at maximum output, preventing spectral shifts that can occur in less powerful air-cooled systems.

Precision Environmental Control: The SX75 offers a tighter tolerance for BPT ($\pm 1^\circ\text{C}$) and chamber temperature, providing the high level of repeatability required for scientific research.

Complex Moisture Simulation: Beyond simple rainfall, the dual spray and rear spray functions allow you to simulate the specific effects of evening dew and backside condensation.

High-Irradiance BPT Management: Even at $180\text{W/m}^2$, the sophisticated airflow and cooling systems allow you to maintain a Black Panel Temperature as high as $95^\circ\text{C}$ for specialized heat-resistance testing.

Test Procedures

1. Equipment Calibration

Before beginning a high-irradiance run, verify the xenon lamp's spectral output using a calibrated radiometer. Ensure the water cooling system is operating with deionized water of the correct conductivity.

2. Sample Loading

Mount your test specimens into the holders. Place them on the rotating rack, ensuring they are evenly spaced. If testing fewer than 54 samples, use blank plates to maintain the aerodynamics of the chamber.

3. Cycle Programming

Define your test protocol via the touch-screen interface. For ultra-accelerated tests, set the irradiance to $180\text{W/m}^2$ and configure the corresponding BPT and humidity values. Select the spray intervals (front, rear, or dual) based on your target climate.

4. Test Initiation and Monitoring

Start the test and monitor the stability of the arc. The SX75 automatically adjusts the lamp power to compensate for aging. Regularly check the BPT and RH logs to ensure the chamber is operating within the specified $\pm 1^\circ\text{C}$ and $\pm 5\%\text{ RH}$ tolerances.

5. Evaluation

Upon completion, the system safely shuts down the lamp and cools the chamber. Remove your samples and perform visual, mechanical, or colorimetric assessments to determine the degree of degradation.

FAQ

1.How does the SX75 achieve ultra-accelerated aging without compromising test reliability?

The combination of high irradiance, precise temperature control, and stable spectral output allows you to accelerate degradation while maintaining controlled and repeatable conditions.

2.Is high-irradiance testing suitable for all materials?

You should evaluate material heat sensitivity before selecting maximum irradiance. The SX75 allows you to adjust irradiance and BPT to match material limitations.

3.What is the advantage of rear spray and dual spray functions?

These modes enable you to assess backside moisture effects, condensation-related degradation, and delamination risks that cannot be evaluated with surface spray alone.

4.Can the SX75 be used for standard compliance testing?

Yes. You can configure the system to meet standard irradiance and temperature levels for ISO, ASTM, SAE, JIS, and JASO test methods.

5.How is irradiance consistency maintained over long test durations?

The system uses closed-loop feedback control to continuously adjust lamp power and compensate for lamp aging.

6.What types of products benefit most from the SX75?

Materials and components requiring rapid durability assessment, such as automotive parts, coatings, plastics, and high-performance polymers, benefit most from this system.
