Exhaust gas analyzer 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 Lambda coefficient measurement is the most common. The principles used for CO sensors (and other types of gas) are infrared gas sensors (NDIR) and chemical gas sensors. "Carbon monoxide sensors are" used to assess the CO amount during an MOT test. In order to be used for such test it must be approved as suitable for use in the scheme. In UK a list of acceptable exhaust gas
Diesel exhaust to low levels. The $11.5 million Diesel Exhaust in Miners Study (DEMS) followed 12,315 miners, controlling for key carcinogens such as cigarette smoke, radon, and asbestos. This allowed scientists to isolate the effects of diesel fumes. For over 10 years, concerns have been raised in the USA regarding children's exposure to DPM as they ride diesel-powered school buses to and from school. In 2013, the Environmental Protection Agency (EPA) established the Clean School Bus USA initiative in an effort to unite private and public organizations in curbing student exposures. Diesel particulate matter (DPM), sometimes also called diesel exhaust particles (DEP),
