Meizu Technology, looking for a programmable constant temperature and humidity tester manufactured by Hongzhan Instruments, high and low temperature alternating heat and humidity test chamber


On December 2, 2009, the RP-225U programmable constant temperature and humidity tester from Hongzhan Instruments was successfully delivered to Zhuhai Meizu Technology Co., Ltd. and passed the final acceptance test.



Zhuhai Meizu Technology Co., Ltd. is a leading high-tech company specializing in the research, development, and production of multimedia devices. Founded in March 2003, the company spent its first year in preparation before entering a period of rapid growth. By 2007, it had achieved an output value in the hundreds of millions of yuan, and successfully challenged the traditional market structure where imported products were seen as high quality but expensive, while domestic ones were low-cost but low-quality. Meizu managed to break this pattern and gain significant market share in the domestic multimedia player industry.

The company has consistently focused on innovation and quality, aiming to serve a refined consumer base with elegant and functional products. Over the years, Meizu has expanded its presence internationally, gaining recognition in Japan, South Korea, and Europe.

Driven by a spirit of perseverance and continuous improvement, Meizu has invested heavily in talent, advanced technology, and strategic partnerships with global industry leaders. This effort led to the establishment of a state-of-the-art R&D and manufacturing center, known as the Meizu Technology Building, which significantly enhanced the company’s hardware and software capabilities.
In 2008, Meizu set its sights on even greater ambitions, aiming to move beyond its current success. With the launch of the Meizu M8, a multifunctional device combining communication and multimedia features, the company aimed to reshape the domestic market and bring more excitement into people's lives through its innovative products and strong brand spirit.
