Our company chose the name "Chang Ai" to mean taking responsibility, having the courage to meet challenges, and never giving up! We believe that only a company with these kinds of spirit can endure, maintain continuous innovation, reach new heights, and create miracles one by one.
In the early 21st century, China' s high-end gas analyzer market was dominated by international brands. Equipment was expensive, service was slow, and industry development was constrained.
These challenges motivated Chang Ai' s two founders—Chen Yaping and Pu Youqiang. Starting from a laboratory, they dedicated themselves to the independent development of sensors and algorithms. With a solid technical foundation, they pioneered a new path for domestically produced high-end gas analyzers.
In the winter of 2004, Shanghai Chang Ai Electronics Technology Co., Ltd. was officially founded in a small R&D studio in Pudong, Shanghai, covering less than 100 square meters.
"Chang" symbolizes everlasting light, while "Ai" stands for precise protection. The brand name embodies the founders' original mission and their commitment to earning custmoers' trust.
In the early days, the team faced multiple challenges: technical, financial, and market-related. To solve the stability issues of sensors, they spent long hours on the laboratory; to secure their first order, they took their equipment to a steel mill and conducted continuous tests under high-temperature conditions, ultimately winning trust through reliable data.
In 2005, Chang Ai launched China' s first online oxygen analyzer that did not require a reference gas, achieving a technological breakthrough with international-level precision and better cost-efficiency. By 2008, this product was selected for the environmental monitoring system of the Beijing Olympics, marking the first time domestically produced analyzers reached an international high-standard stage.
Building on the success of the Olympic project, Chang Ai gradually established a complete industrial chain.
Over the decade, the company undertook multiple national-level research projects, obtained over a hundred patents, and expanded its product range from single analyzers to multi-parameter systems, serving more than 20 countries and regions worldwide.
As the industrial world embraced digitalization, Chang Ai seized the opportunity to transform and innovate.
