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.
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.

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.
