Nitric Oxide (NO) Detection

Portable & fixed-point NO2 detectors for healthcare, pharmaceuticals, chemical manufacturing, agriculture, and environmental testing.

About Nitric Oxide Detection

Nitric Oxide, a colorless gas with a sharp, sweet odor, plays a critical role in various industries, including semiconductor manufacturing for chip production, and as an intermediate in the synthesis of nitric acid.

It’s also used for its vasodilating properties in medical applications. However, NO can rapidly form nitrogen dioxide (NO2) in the air, which is toxic, and therefore requires rigorous environmental monitoring and control in the workplace.

Common Challenges

  • Rapid conversion to toxic NO2 in the air, posing health risks.
  • Detection at low concentrations due to its colorless nature.
  • Maintaining accurate monitoring and control systems to ensure workplace safety.

Current Guidelines


  • PEL-TWA: 25 ppm (30 mg/m³)
