Infrared Gas Detection Pros & Cons

Advantages of Infrared Gas Detection

Does not require the presence of O2

Not affected by typical catalytic poisons

Lower power consumption than catalytic bead sensor

Accuracy very stable

Sensor available for 100% v/v CH4

5 year MTBF - lower cost of ownership over lifespan


Limitations of Infrared Gas Detection

Cannot detect hydrogen, acetylene, carbon disulfide

High cost compared to catalytic bead sensor

Affected more by changes in temperature and pressure.

Response is linear to methane but non-linear to other hydrocarbons
