You must know BOTH* to get maximum combustion efficiency ! How much money is going u p the flue in unburned fuel losses? Is too much air result ing in excessive heat losses? You must know both facts—simultaneously —to get optimum combustion. No instrument t h a t measures only one of these interdepend ent factors can give you the full information you need. Bailey offers a choice of two direct ways to maintain a continuous and simultaneous double check on these factors that determine combustion efficiency. The portable, light weight Bailey H E A T P R O V E R Analyzer indi cates both; the Bailey Oxygen-Combustibles Analyzer-Recorder records both on a single chart. Both instruments measure excess air, regardless of fuel or fuels being burned, and per cent of combustibles influegas. Either of these Bailey instruments can save you far more than their cost in spotlighting combustion inefficiencies. Ask your Bailey engineer or write for product specifications.
