Two radiometer sensors with different wavelength ranges Installed on the transmission shaft and positioned on the center line of every two lamp tubes.
Full scanning and automatic irradiance compensation ensure uniformity and accuracy. Carry out in groups to ensure the ratio of the irradiation amount of ~ and ~ or the two bands, and at the same time ensure that the center line of the module test surface and the both sides of the module are evenly irradiated.
The attenuation of irradiance over time will not cause distortion of the total irradiation, and relatively extends the service life of the lamp.

Two-box structure
The inner wall of the test chamber is made of stainless steel, which is not decomposed by ultraviolet light, is corrosion-resistant and beautiful. The outer part is made of steel plate spray-painted, and the color can be selected by the customer. A channel steel angle iron frame is used between the inner wall and the outer body, making the whole structure strong and durable. The entire laboratory has a beautiful appearance.
According to the provisions of the standard, a row of lamp tubes is designed indoors to meet the needs of two groups of sample solar panels being tested at the same time. The distance between the centers of the lamp tubes can be adjusted as the sample sizes are arranged. , fully refer to the provisions of the standard. A solar panel stand is designed indoors to meet the installation of solar panels of different sizes. The height is based on the sample or customer requirements, and the distance from the lamp can be adjusted to meet different samples and adjust the irradiance of different requirements. Installation The lamp stand is a special device that can install lamps that meet the size of the sample, parallel to the sample. After the sample is installed, the two ends and the upper and lower gaps are filled with special templates so that the surface and back of the sample are in different temperature and humidity environments. The surface is exposed to light, temperature, humidity and rain, and the back is in natural flowing air, simulating a real environment. . A fan is used on the back of the sample to move the air and keep it consistent with the environment.
The connecting wires at both ends of the lamp are specially designed to ensure that they will not be corroded by water and cause a short circuit under high indoor humidity or spray conditions. The installation design of the lamp is simple and convenient, and customers can easily replace the lamp.
Install a set of ultraviolet radiation measurement and control instruments to detect indoor ultraviolet irradiance and cumulative irradiation to meet the standards. The radiation measurement and control instrument is a product produced by Beijing Normal University and has passed national testing. More realistic simulation of environmental testing.
A special air-conditioning device is installed indoors, with air heating and water heating heaters arranged to meet the required temperature and humidity in the test room. The circulating air system keeps the indoor temperature and humidity uniform. Several nozzles were reasonably designed in the gaps between the lamp tubes on the lamp stand to conduct a simulated rain test on the samples. This simulated the environment of a sudden heavy rain when the temperature was the highest in summer and the light was strong. The surface temperature of the sample dropped sharply, and at the same time the sample Condensation is generated on the back, subjecting the sample to the most severe environmental test.
A ventilation device is installed on the top, and the instrument is automatically controlled. When light and condensation alternate, the indoor temperature and humidity can be quickly and uniformly maintained, and ozone gas generated by ultraviolet light is eliminated.
Three-temperature and humidity control
Cycle
The first-level photochemical reaction is not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to the temperature change. Generally speaking, as the temperature increases, the reaction rate increases. Therefore, temperature control is very important during the exposure test. It is more important to match the test temperature used in the accelerated test with the temperature encountered by the material in actual applications. The temperature setting in the device can be anywhere from ℃ to ℃, depending on the light level and indoor ambient air temperature. The temperature adjustment of the equipment is accomplished by using a controller with a microcomputer calculation function to direct a series of systems in the equipment such as air heaters, water heaters, etc.
Moisture circulation
As the temperature increases, the destructive power of moisture on materials will increase dramatically. Therefore, temperature control is a basic requirement during moist exposure. Furthermore, to produce an accelerated effect, it is necessary to maintain a high temperature environment during the moist exposure process. The condensation process temperature setting in the equipment can be any point from ℃ to ℃.

During the cycle test, there is a test section that is a dark condensation process, which requires higher temperature saturated water vapor to be generated in the box. When the water vapor encounters a relatively cold When the sample surface is exposed to water, dew will condense on the sample surface.
