an ISO9001 Company

The Figaro Gas Sensor is a gas sensitive semiconductor which was developed by Naoyoshi Taguchi and has been marketed by Figaro Engineering Inc. since 1968. The Taguchi Gas Sensor (TGS) is a sintered n-type semiconductor bulk device. Most TGS sensors are composed of sintered tin dioxide whose resistance in fresh air is very high and drops dramatically in the presence of reducing gases such as combustibles (methane, propane, CO, hydrogen, etc.), volatile organic vapors (alcohol, ketone, esters, benzols, etc.), and many others.

Figaro Engineering Inc.

Figaro Engineering Inc. was formed as a private enterprise in 1962 by N. Taguchi. The company began to mass-produce and sell TGS sensors starting in October 1968. Headquartered in the northern part of Osaka Japan, Figaro has been the worldwide leader in gas sensing technology for more than 30 years, with a commitment to developing the finest gas sensors which offer both low cost and long life. The company was acquired by Tokuyama Soda Co. Ltd. in February 1986.

ISO Certification

Figaro Engineering Inc. has achieved ISO 9001 certification. As acknowledged in the Japanese media, Figaro is the first company of its size in Japan to have successfully achieved this status and remains the only gas sensor manufacturer from Japan to obtain this certification.

Patents and Industry Awards

As a leader in gas sensing research, Figaro has obtained nearly 300 patents worldwide, including 245 in Japan and 6 each in the United States, U.K., West Germany, Canada, France, and Italy.
