The SUGA GX75 7.5kW Xenon Weather Meter is a high-performance xenon arc aging tester, also known as a xenon weathering chamber. This equipment simulates key environmental factors in nature—including ultraviolet radiation from sunlight, temperature variations, humidity fluctuations, and periodic rainfall—to accelerate the aging of various materials or finished products. Its core function is to evaluate the weather resistance of materials under long-term outdoor exposure and scientifically predict product service life. The device is widely used in materials science research, new product development, production quality control, and compliance verification with industry standards. It is applicable to plastics, industrial coatings, textiles, automotive exterior components, packaging materials, and more, making it an essential tool for modern industrial weatherability testing.
Working Principle
The SUGA GX75 xenon weathering chamber uses a 7.5kW long-life xenon arc lamp to simulate the solar spectrum (covering 300–400 nm ultraviolet and visible light regions), paired with an automatic irradiance feedback control system to precisely maintain stable irradiance on the sample surface. The chamber is equipped with a circulating air system, heaters, a humidity generator, and adjustable valves for precise control of temperature and humidity. A water-cooling system for the xenon lamp ensures long-term stable operation. The equipment supports continuous exposure or light/dark cycling and can optionally include a spraying function to simulate rainfall. It is suitable for accelerated aging tests of various materials and complies with multiple international standards such as ISO 4892-2. JIS K7350-2. and SAE J2527.
Detailed Operating Procedure
The SUGA GX75 7.5kW xenon weathering tester is a high-precision instrument for simulating natural environmental conditions and accelerating material aging, widely used for quality evaluation in coatings, plastics, rubber, and automotive materials. The standardized operation and safety procedures are as follows:
Basic Usage Steps
Installation and Preparation:
Install the device in a controlled laboratory environment with ambient temperature at 23 ± 5 °C and relative humidity at 65 ± 10 % RH.
Power supply must meet 3-phase 200V, ~55A, 50/60Hz requirements, equipped with a properly rated 3-phase 200V residual current circuit breaker.
Connect two separate water systems: one supplying pure water for humidity control and surface spraying; another providing tap or cooling tower water for xenon lamp cooling, with inlet pressure maintained at 0.1–0.2 MPa.
Correctly connect drainage and exhaust systems to ensure proper removal of wastewater and fumes.
Startup and Preheating:
Switch on the main power with residual current protection.
Select the desired test program on the control interface. The device can store up to 15 programs, each lasting up to 99 hours and 59 minutes.
Start the xenon lamp; the system automatically executes the ignition sequence and stabilizes irradiance in the preset range (typically 40–120 W/m² at 300–400 nm).
Sample Installation:
Recommended standard sample size: 150 × 70 × 1 mm; maximum capacity: 63 samples. Samples are mounted on a uniformly rotating sample rack at 2 rpm.
Ensure sample surfaces are clean, free of oil or contaminants, and securely mounted according to relevant standards to prevent detachment during testing.
Test Execution:
Choose operational mode according to experimental requirements:
Light exposure only
Light exposure with surface spray (simulating rainfall)
Complete darkness
Darkness with backside spray (simulating condensation)
Darkness with dual-side spraying
Multi-stage cyclic tests are supported.
Real-time monitoring via the 8.4-inch color touchscreen allows automatic adjustment of:
Black panel temperature (BPT): 63–110 °C ± 2 °C
Chamber water temperature: 38 °C ± 2 °C
Relative humidity: 50 ± 5 % or 95 ± 5 %
Irradiance level: automatically controlled by PAT feedback system
Completion and Maintenance:
The system automatically turns off the xenon lamp at the end of the test.
Remove samples only after the chamber reaches a safe temperature.
Regular maintenance includes replacing xenon lamps at the end of their service life, changing pure water filters, and checking cooling water quality.
Usage Precautions
Safety Requirements:
Do not touch the xenon lamp or internal components before the equipment fully cools to avoid severe burns.
The system includes an emergency stop button and multiple safety protections (over-temperature, overcurrent, automatic power-off on door opening).
UV radiation is strong when the lamp is operating; never remove or cover the observation window.
Operational Guidelines:
Use pure water in the humidity and spray systems to prevent scaling or blockages.
For xenon lamp cooling, use tap or cooling tower water below 25 °C at ≥6 L/min.
Avoid running the chamber empty to prevent temperature anomalies.
Calibration and Maintenance:
Irradiance sensors should be professionally calibrated at least once per year.
Xenon lamps generally last 1.000–2.000 hours and must be replaced when reaching this limit.
Inspect water filters, circulation pumps, and spray nozzles monthly to ensure normal operation.
