Exhaust gas analyzer of this sensor and to create smaller devices.Typical NDIR sensors cost in the (US) $100 to $1000 range. Used by older aircraft, the Cambridge Mixture Indicator displayed air-fuel ratio by measuring the thermal conductivity of exhaust gas. It was manufactured by the Cambridge Instrument Company. This device was installed on airplanes in the 1930s, including the Lockheed Model 10 Electra flown by Amelia Earhart on her last flight. Exhaust gas analyzer An exhaust gas analyser or exhaust CO analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the
Inert gas generator sometimes confused with "flue gas systems", which draw inert gas from the boiler systems of the ship. Flue gas systems do not have a burner but only "clean" and measure the air before delivering it to the cargo hold. Inert gas generator Inert gas generator (IGG) refers to machinery on board marine product tankers. Inert gas generators consist distinctively of a gas producer and a scrubbing system. Diesel is burned using atmospheric air in a combustion chamber and the exhaust gas collected, the resulting exhaust gas contains less than 5% oxygen, thereby creating "inert gas", which mainly consist of Nitrogen
