Product Description
- TGS821 Hydrogen (H2) Gas Sensor 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
TGS821 Hydrogen (H2) Gas Sensor Applications:
* Hydrogen gas detection for:
- transformer maintenance

- etc.
The sensing element of Figaro Gas Sensors is a tin dioxide (SnO 2 ) 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 in conductivity to an output signal which corresponds to the gas concentration.
The TGS 821 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.
