A range of gas sensors from Figaro utilising tin dioxide (SnO2) semiconductor technology. In clean air the devices have low conductivity which increases in the presence of a detectable gas. A simple electrical circuit can be used to convert the change in conductivity to an output signal proportional to gas concentration.
• Type TGS821 has high sensitivity and selectivity to hydrogen gas. The sensor can detect concentrations as low as 50ppm, making it ideal for a variety of industrial applications. • Types TGS822 & TGS823 have high sensitivity to the vapours of organic solvents and a variety of combustible gases such as carbon monoxide, making them good general purpose sensors, type TGS823 has a ceramic base able to withstand temperatures of up to 200°C. • Type TGS826 has high sensitivity to ammonia gas and can detect concentrations as low as 30ppm. It is ideally suited to critical safety-related applications such as the detection of ammonia leaks in refrigeration systems and ammonia detection in the agricultural field.
