Although the application range of environmental testing equipment is wide and the market prospects are promising, under the temptation of huge market cakes, objectively, many competition chaos has also emerged. According to data analysis, there are currently about 3,000 manufacturers and distributors operating environmental test equipment in China. Although there are many enterprises, they have different levels. In order to improve performance, some small and medium-sized enterprises that lack technical strength, lack of brand influence and scale often can only lower prices, but due to poor equipment quality, it is difficult to guarantee after-sales service and it is difficult to win market reputation. As the product competition environment gradually matures, consumers pay more attention to product quality, and consumption becomes more rational. Enterprises must have solid core competitiveness to avoid being eliminated. Beijing Yashilin Testing Equipment Co., Ltd., which has many years of experience in environmental testing equipment production and marketing, has insisted on independent product technology research and development, continuous innovation, forging ahead, and successfully applied for multiple product technology patents, which has formed a significant advantage on the technical level. Yashilin's R & D center is set up by several overseas returnees with internationally renowned environmental testing company experience. It closely follows customer needs for product research and development, and cooperates closely with scientific research institutions such as Chinese Academy of Sciences, China Aerospace, Tsinghua University, Peking University The accumulation of marketing experience and the creation of technological advantages have created Yashilin's leading position in the industry. The ozone generation of the Beijing Yashilin ozone aging test chamber is to generate ozone through a high-pressure discharge generator. This generator has the advantages of mature technology, stable operation, long service life, and large ozone output (up to 1Kg / h for a single machine) The most widely used ozone generators in related industries at home and abroad. When using a silent discharge tube, the ozone concentration can be adjusted by adjusting the voltage applied to the generator, the electrode size, the oxygen flow rate, or the reduced air flow rate. These adjustment methods should keep the ozone concentration within the tolerance range of the concentration specified in 8.1 of the standard GB / T 7762-2003. In addition, when the test box is opened to place or check the sample, the ozone concentration should be restored to the concentration specified in the test within 30 minutes. The ozone concentration entering the ozone box should not exceed the test specified concentration under any circumstances.
