RS Components 1346591 Gas Instruments

Figaro's range of gas sensors utilizing tin dioxide (SnO2) semiconductor technology. In clean air,the conductivity of these devices is very low,and in the presence of detectable gases,the conductivity increases. A simple circuit can convert changes in conductivity into an output signal proportional to the gas concentration. •Type TGS821 has high sensitivity and selectivity to hydrogen. The sensor can detect concentrations as low as 50ppm,making it ideal for a variety of industrial applications. •Types TGS822 and TGS823 have high sensitivity to a variety of combustible gases such as organic solvent vapors and carbon monoxide and are a good general-purpose sensor. Type TGS823 has a ceramic base and is able to withstand temperatures up to 200 u00b0C and can detect temperatures as low as 30ppm concentration. It is ideally suited for critical safety-related applications such as detection of ammonia leaks in refrigeration systems and ammonia detection in the agricultural sector.
