Gas Analyzers

Analyzing air pollution is the first step toward preserving a clean atmospheric environment. 

Gas analyzer

FUJI developed the first infrared gas analyzer in Japan to use mass-flow sensors. Since then, we have supplied customers with various types of gas analyzers to support environmental preservation and control efforts. These efforts include measurements of atmospheric pollution and detection of low density of SOx and NOx, generated by incinerating facilities and boilers. FUJI's gas analyzers are widely used to monitor the atmosphere to help maintain a cleaner natural environment.
