T h e Burr ell CO ^Indicator measures the C 0 2 content of the stack gas in less than a minute and directly indicates the value on a long, clear, easily read scale. The Burrell Combustion Indicator, included with each instrument, quickly converts the C 0 2 reading and the stack temperature into terms of combustion efficiency and heat loss and provides directions for bettering firing conditions. The instrument is easily manipulated and unskilled operators have little trouble obtaining accurate, reproducible results. No preliminary adjustments are required, no valves to check, no waiting for liquids to drain, it is always ready for instant use. The Burrell C02 Indicator is constructed of sturdy, light weight plastic and metal parts and contains a non-corrosive granular absorbent. The cartridge containing the absorbent will give many analyses and is changed in a few seconds without the use of tools. The Burrell CO^ Indicator, aspirator with rubber tubing, two metal probes and the Combustion Indicator are supplied in a handy carrying case. A metal thermometer is recommended for taking stack temperatures. For complete information request Burrell CO2 Indicator Bulletin 206. BURRELL
