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
Exhaust gas the European Union's man-made CO emissions, with passenger cars contributing about 12%. European emission standards limit the CO emissions of new passenger cars and light vehicles. The European Union average new car CO emissions figure dropped by 5.4% in the year to the first quarter of 2010, down to 145.6 g/km. Vehicle exhaust contains much water vapour. There has been research into ways that troops in deserts can recover drinkable water from their vehicles' exhaust gases. Emission standards focus on reducing pollutants contained in the exhaust gases from vehicles as well as from industrial flue gas stacks and other air
