Figaro Engineering Inc. products

The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductorwhich has low conductivity in clean air.  In the presence of a detectable gas,the sensor`s conductivity increases depending on the gas concentration inthe air.  A simple electrical circuit can convert the change in conductivity toan output signal which corresponds to the gas concentration.The TGS 816 is not only sensitive to a wide range of gases, it also has a ceramicbase which can withstand severe environments up to 200°C.  Ithas highsensitivity to methane, propane, and butane, making it ideal for natural gasand LPG monitoring.  The sensor can detect a wide range of gases, makingit an excellent, low cost sensor for a variety of applications.
