The market of testing equipment can be roughly divided into laboratory testing equipment and production line testing equipment according to their uses. In 2013, the new demand for laboratories was insufficient, and major manufacturers in the industry tried to seize more market share in the production line market. The market for laboratory testing equipment is very mature, and many equipment are similar to the principle of traditional lamp testing equipment such as fluorescent lamps. Its customer base is also relatively single, mainly for third-party testing institutions, universities, laboratories and large enterprises to build their own optical laboratories. At the same time, the laboratory testing equipment industry has not changed seasonally like other market segments, and it is entirely driven by demand. After years of development, this small segment of the market began to appear saturated. In China, laboratory testing equipment manufacturers are mainly concentrated in Hangzhou in the Yangtze River Delta region. Hangzhou gathers equipment enterprises with cross-industry chain development in the industry Hangzhou Zhongzhong, listed faraway Optoelectronics, Zhejiang University three leading enterprises with the background of colleges and universities, their testing equipment level also represents a high level in the country and can be compared with the international level. In addition, there are also many small and medium-sized testing equipment manufacturers operating some small market segments. The demand for the laboratory is somewhat lower than last year. The laboratory can generally invest once, unless there are new test items or new standards are introduced to purchase new equipment. At present, there are very few new laboratories, and the newly built laboratories planned by the manufacturers have been basically completed. Liu Shen, head of the Hangzhou Zhongzhong sales center, believes that SMEs are unlikely to build their own laboratories, so the demand for laboratory testing is gradually returning to the market from the explosive growth in the early years.
