SX75 7.5kW Super Xenon Weather Meter
Category：Carbon Arc Aging Tester
Introduction
The 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
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.
Accessories

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.
