TGS813 & TGS816 Combustible Gas Sensors Combustible gas sensors from Figaro utilising tin dioxide (SnO2) semiconductor technology providing an output proportion to gas concentration. These low cost sensors can detect a wide range of combustible gases making them an ideal choice for a wide variety of applications. Type TGS813 has a nylon 66 housing and base; type TGS816 has a metal housing with a ceramic base which is capable of withstanding temperatures of up to 200°C. Typical applications include domestic gas leak detectors and alarms, and portable gas detectors. • High sensitivity to methane, propane and butane
• Long life and low cost
• Utilises simple electrical circuit
