Catalytic Gas Detection Pros & Cons

Advantages of Catalytic Gas Detection

Relatively low cost

Accurate and linear over sensor detection range relative to calibration gas

Broad band sensor

Long history, proven technology


Limitations of Catalytic Gas Detection

Unable to identify type of gas detected

Requires sufficient O2 to support operating principle

High power consumption

Not fail safe - Poisoned by: sulfurs, silicones, Phosphors & leads - Inhibited by: chlorinated & fluorinated hydrocarbons

Combustible gas readings may not reflect the true concentration of a combustible gas hazard.
