net FIGARO PRODUCT INFORMATION TGS 821 - Special Sensor for Hydrogen Gas Features: * High sensitivity and selectivity to hydrogen gas * Good repeatability in measurement and excellent stability * Uses simple electrical circuit * Ceramic base resistant to severe environment Applications: * Hydrogen gas detection for: - transformer maintenance - batteries - steel industry usage - etc.
The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air.
In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air.
A simple electrical circuit can convert the change i...
