In 1952, Richard Steel, John Crockett and Ronald Mudie founded SFUMEI in the UK. The company started out as an electronics manufacturer, with products including capacitor boxes, waveform generators and a successful mains (AC) regulator/controller series. It was not until Richard Steel met Charles Munday, which was studying the development of advanced paramagnetic oxygen sensors at the time, that SFUME began its current business path.

Through joint efforts, the company's team has produced a revolutionary and innovative product - a paramagnetic measurement cell that accurately and stably measures oxygen content. This innovation is a milestone and laid the foundation for Shifumei's business. After more than 60 years of continuous development, Shifumei has now become a global expert in the field of gas sensing. In 1961, Shifumei integrated sensors into paramagnetic analyzers, and its reputation in the industry also steadily improved over the next 40 years. After being acquired by SBG, an advanced supplier of instrumentation and control in 1999, SFUME has successfully transformed from an innovative company to an expert in gas analysis in the 21st century.

Adhering to the pioneering business philosophy, the company provides customer-centric sensing solutions, and has developed a series of benchmark innovative products, including the following innovations: solid electrolyte low-contact reaction zirconia measuring tank, dedicated to high-voltage oxygen-enriched Environmental SERVOTOUGH OxyExact process analyzer, portable paramagnetic oxygen analyzer, true thermal conductivity sensor, smaller TDL laser monitoring. The company has opened business, service and system engineering centers in Shanghai, China, Houston, Texas, Zoetermeer, Netherlands, Mumbai, India, Sao Paulo, Brazil and Valley Point, Singapore, and established a global network layout.

In 2008, the company opened advanced technology centers in Crowborough, UK, and acquired and merged Contrôle Analytique and Delta F in 2007 and 2010, respectively (its factory in Boston is now equivalent to a STFUME Tech Center with full manufacturing capabilities. ), continues to maintain professional advantages in technology and manufacturing. Shifumei incorporates its globally advantaged sensor products under the rapidly developing Hummingbird brand and expanded its product applications to the medical and industrial OEM industries in 2011.
