GX75 7.5kW Xenon Weather Meter

The GX75 7.5kW Xenon Weather Meter is a high-performance accelerated aging system designed to artificially reproduce the complex stresses of both indoor and outdoor environments. By utilizing a powerful 7.5kW water-cooled xenon arc lamp, this instrument simulates sunlight, temperature, humidity, and rainfall to accelerate the degradation of materials and predict their operational lifespan. Whether you are performing standard durability tests or advanced ultra-accelerated research, the GX75 provides the precision and irradiance control required to evaluate material performance with global consistency.

Applications

GX75 7.5kW Xenon Weather Meter is designed to artificially reproduce indoor and outdoor environments such as sunlight, temperature, humidity, and rainfall, accelerating the aging of products and materials to predict their service life. The product range spans from global standard weathering testers to the latest premium accelerated models.

Standards

The GX75 meets stringent international standards, including:

ISO 4892-2. ASTM G155. SAE J2527 (automotive coatings)

JIS K7350-2 (Japan Industrial Standard for weathering tests)

AATCC TM16. GB/T 16422.2 (China’s national standard for xenon-arc exposure)

These standards ensure reliable evaluation of material durability, colorfastness, and aging resistance.

Features

High-Intensity Acceleration: The 7.5kW water-cooled lamp allows for significantly higher irradiance levels than air-cooled systems, enabling you to finish life-cycle predictions in a shorter timeframe.

Versatile Simulation Cycles: You can program complex cycles that include light exposure, dark periods, rainfall (front spray), and evening dew (rear spray) to replicate real-world diurnal variations.

Superior Irradiance Control: The system maintains precise control over the 300--400nm range, ensuring that the spectral distribution remains consistent even as the lamp ages.

Dual-Spray Functionality: Unique spray configurations allow for moisture simulation on both the front and back of the samples, which is critical for assessing materials prone to delamination or backside corrosion.

Wide Temperature Range: With a BPT capability up to $110^\circ\text{C}$, you can simulate the extreme heat found on automotive dashboards or in desert climates.

FAQ

1. How does the GX75 ensure long-term irradiance stability during extended tests?

You benefit from a closed-loop irradiance control system combined with automatic calibration. The controller continuously compensates for lamp aging, ensuring that the irradiance in the 300–400 nm range remains within the specified tolerance throughout long-duration exposure cycles.

2. Why is a water-cooled xenon lamp used instead of an air-cooled design?

Water cooling allows the 7.5kW xenon lamp to operate at higher and more stable irradiance levels while effectively removing excess heat. This design reduces thermal drift, improves spectral stability, and supports higher acceleration factors compared with air-cooled systems.

3. Can you test materials that are sensitive to backside moisture or internal delamination?

Yes. The dual-spray system enables independent surface spray and backside spray, allowing you to evaluate materials that are susceptible to moisture ingress, adhesive failure, or backside corrosion under realistic outdoor exposure conditions.

4. How do you control and verify the sample surface temperature during testing?

Sample surface temperature is controlled using a Black Panel Thermometer (BPT). The system maintains BPT within ±2°C of the set value, ensuring repeatable thermal stress conditions that closely match international weathering test standards.
