Nitric Oxide gas (NO)
Nitric Oxide gas also known as Nitrogen Dioxide is used in the medical and industrial industry. It is an anthropogenic gas released by contact between nitric acid and many compounds. It can be found in many industries like wood (sawdust), explosives (dynamite), metals (engraving) and in high heat welding applications. It is partially responsible for atmospheric pollution exhausted by diesel powered engines. It is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack.
