TGS2611 is a semiconductor type gas sensor which combines very high
sensitivity to methane gas with low power consumption and long life.

 

Due to miniaturization of its sensing chip, TGS2611 requires a heater current

of only 56mA and the device is housed in a standard TO-5 package.

 

The TGS2611 is available in two different models which have different external
housings but identical sensitivity to methane gas.

Both models are able to satisfy the requirements of performance standards such

as UL1484 and EN50194.

TGS2611-C00 possesses small size and quick gas response, making it suitable

for gas leakage checkers.

TGS2611-E00 uses filter material in its housing which eliminates the influence
of interference gases such as alcohol, resulting in highly selective response to
methane gas.

 

This feature makes the sensor ideal for residential gas leakage detectors which

require durability and resistance against interference gas.
