Our History

San Fong Instruments was set up in December 1987. For more than 30 years, it has been the goal to upgrade the industrial instruments with the progress of technology and manage the industry production with controlling. Therefore, SFI leads in various instruments and equipment since the Europe, the United States, Japan and other developed country to the related industry such as oil, chemistry, food, dyeing machine, HVAC and so on. SFI hopes to offer our customers the best product with the best quality and the best services in this era of information explosion.

SFI sold European Bourdon Haenni products in Taiwan in the beginning of the establishment. After many years, Bourdon Haenni has a well reputation of excellent quality product in the process instruments. In 2005, Baumer group acquired Bourdon Haenni, which expands SFI product line in factory automation such as inductive sensor, ultrasonic sensor, photoelectric sensor, capacitive sensor, encoders, industrial camera and it will helps to fit all in one demands. In addition, SFI also is the distributor of European Diehl (Sappel) production of the water meters, German Nöding and the Swiss Keller production of the transmitters which are all our highly recommend to use.

Our Mission and Goal

San Fong instruments hopes to create SFI existing value by offering the customers the best services with the most satisfying. "Honesty and credibility" is the basic concept of all SFI staff. SFI aims to “Professional Distributor”, “Excellent Quality”, “Reasonable Price” and “Best services” for all SFI customers and wishes all SFI staff could progress with the technology and make the most efforts together to create the better future.
