This feature makes the sensor ideal for residential gas leakage detectors which require durability and resistance against interference gas. 

Specifications: 
1) Target gases : Butane, LP gas 
2) range500 ~ 10,000 ppm 
3) sensitivity (change ratio of Rs) : 0.56 ± 0.06 
4) Circuit Voltage5.0±0.2V DC/AC 
5) Heater Voltage5.0±0.2V DC/AC 

Features of gas sensor TGS2610: 
1) High sensitivity to combustible gases 
2) Low power consumption 
3) High sensitivity to methane, propane and butane 
4) Long life and low cost 
5) Uses simple electrical circuit 
6) Small size 

Application of gas sensor TGS2610: 
Domestic gas leak detectors and alarms 
Portable gas detectors 
Combustible gas and vapor detection
