CO 2 / CO guide
CO 2
Carbon dioxide
Carbon dioxide ( CO 2 ) is a colourless gas with applications in the food , oil , and chemical industries , and is used in many pressurized gas tools .
Many industrial processes need to monitor CO 2 for process control and efficiency . Additionally , CO 2 is the largest contributor to global climate change , so emissions are also measured by industrial plants to prove compliance with environmental regulations .
Since it is present in air at trace levels , CO 2 is often encountered as a contaminant in high-purity gases , so measurements of very low-level CO 2 must be achieved for this application .

CO
Carbon monoxide
Carbon monoxide ( CO ) is a poisonous , flammable gas which is colourless , odourless , and tasteless . It has applications in the chemical , food , medical and metals industries .
Measuring CO ( along with O 2 ) helps to maintain the combustion reaction at an optimum balance , maintaining safety and reducing fuel costs . CO may also be monitored to avoid impurities in the production of industrial , medical , and UHP gases .
As it is regarded as a criterion pollutant under many environmental standards , any industrial emissions of CO must be monitored to ensure regulatory compliance .
