Since 2005, Blue Moon Import and Export Trading Co., Ltd. (predecessor of Blue Moon Measurement and Control Technology Co., Ltd.) has obtained agency rights for several well-known foreign sensor brands, including ELT from South Korea. After years of trial and error, the ELT carbon dioxide sensor module provided by Blue Moon Measurement and Control has entered various detection equipment enterprises. The founder of Blue Moon began to notice that major domestic detection equipment enterprises have a strong demand for high-quality products. In order to improve the technical quality of domestic sensors, Blue Moon Group takes into account the existing products and adheres to the original intention of producing high-precision and high-quality sensor products. In 2009, with sufficient preparation, we officially entered the pace of independent research and development production, established a subsidiary - Blue Moon Measurement and Control, and developed into a well-known brand in the field of air quality testing equipment. Currently, we have several independent products. Shenzhen Blue Moon Measurement and Control Technology Co., Ltd. was established in 2009 and is a domestic independent research and production manufacturer of high-quality gas/environmental monitoring equipment. For many years, the company has been dedicated to the research and production of air quality detectors and toxic and harmful gas technologies, accumulating a large number of mature solutions and application experience, possessing multiple intellectual property rights, and obtaining nearly 70 patents of various types.
