The Xenon arc weathering test chamber selects long-arc water-cooled xenon lamps as the light source, which can simulate the full solar spectrum. By changing and controlling the light irradiance, temperature (sample rack temperature, chamber temperature), relative humidity, and spray methods, it can simulate the combined conditions of light, heat, and rainfall in outdoor climates to conduct artificial aging tests on samples. This equipment complies with multiple test methods such as GB, ISO, and ASTM, and is suitable for laboratory light exposure tests of various materials and products such as coatings, plastics, rubber, chemical building materials, and automotive parts. It can provide corresponding environmental simulation and accelerated tests for scientific research, product development, and quality control.
Product Features:
1、Closed-loop irradiance control function
The irradiance detection system can measure the irradiance value inside the test chamber and feed it back to the controller. The controller uses the PID algorithm to calculate the dimming signal and output it to the silicon-controlled rectifier regulator, thereby adjusting the power of the xenon lamp and changing the irradiance to achieve stable control of the irradiance.
2、Sample table temperature control function
The sample table temperature includes the black plate temperature and the black standard temperature, and is related to multiple factors such as irradiance, air flow velocity, and test chamber temperature. Among them, the most direct influences are irradiance and air flow velocity. Irradiance is the most important parameter that this equipment needs to control and must be kept stable. Therefore, to adjust the sample table temperature mainly involves regulating the air flow velocity. The sample table temperature control system also adopts closed-loop control, which can keep the fluctuation range of the sample table temperature within 2℃.
3、Test the temperature and humidity control function of the room
The temperature of the test chamber is regulated by heating devices and the proportion of fresh air, while the humidity is controlled by humidifying devices. The temperature and humidity control system of the test chamber also adopts closed-loop control, which can keep the temperature fluctuation within the test chamber within 2℃ and the humidity fluctuation within ±4%.
4、Temperature and humidity control function
When the temperature and humidity control function is running, during the humidity control process, the temperature of the drying air and the water mist is controlled, and then the temperature of the box body is controlled. The coupling control of the two can keep the temperature and humidity inside the box within the control range through the algorithm.
5、Rainproof control function
The rain condition can be simulated by the spray method, which can achieve both front spray and back spray.
6、Xenon lamp cooling control function
Xenon lamps generate a large amount of heat during operation, and water cooling is necessary to ensure their normal operating temperature. This equipment adopts a secondary water cooling scheme. The primary cooling water comes into direct contact with the xenon lamp and uses laboratory grade two water or water of higher purity. The primary cooling water circuit is closed, and the cooling water is recycled, making it less likely to be contaminated by the outside environment.
7、Dynamic Display
The equipment can display the current test parameters in real time, such as the temperature and humidity inside the chamber, irradiance, and the elapsed time of the current test process, etc. It is also possible to view the experimental parameters and data curves throughout the entire test process.

Material of the xenon arc test chamber：
1. The outer shell is made from high-quality A3 steel plates (t=1.2mm), processed using CNC machining, and the surface is coated with spray plastic for a smoother, more attractive finish.
2. The inner shell uses imported SUS304 stainless steel, known for its excellent quality.
3. For insulation, we use a combination of high-density glass fiber cotton and high-pressure polyurethane foam to ensure effective heat preservation.
4. The stirring system features a long-shaft fan motor paired with a multi-wing stainless steel impeller that can handle both high and low temperatures, creating strong vertical airflow circulation.
5. The door and box are sealed with double-layered, high-temperature resistant, and highly elastic sealing strips to keep the testing area tightly closed.
6. A no-reaction door handle is used for easier operation.
7. High-quality fixed PU casters are installed at the bottom of the machine for easy movement.
