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.
