    Carbon monoxide analyzer CO analyzer All industrial

    A. Carbon monoxide is evidence of wasted fuel. With perfect combustion, all the carbon in the fuel burns to carbon dioxide and all the hydrogen burns to water vapor. For less than perfect combustion, fuel loss rises rapidly. In lift trucks adjusted to run smoothly and not adjusted using a CO analyzer, the exhaust CO is usually between 3% and 10%. In our experience trucks with carbureted systems, more than half of …
