NO factors into ozone layer depletion and reacts with stratospheric ozone to form O2 and nitrogen dioxide. Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health.

Elemental Instruments, a division of Ohio Lumex, offers a range of nitric oxide analyzers that provide online, real-time measurements to control and monitor emissions and processes.

Nitric oxide (NO) is a colorless gas and one of the principal oxides of nitrogen. It is an important intermediate in industrial chemistry, forms in combustion systems, and can be generated by lightning in thunderstorms.

At levels of 100 ppm, nitric oxide is dangerous to health and can be lethal. In the U.S., the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) have set maximum exposure limits of 25 ppm (30 mg/m3) over an 8-hour workday.
