Nitrogen Dioxide (NO2)

Nitrogen Dioxide (NO2) is an extremely toxic gas, readily detected by its acrid Chlorine like smell at low concentrations. Concentrations as low as 4ppm can anaesthetise the nose leading to a false sense of security and over exposure. Additionally it will readily combine with water to form Nitric Acid. As it is a component of vehicle and power station exhaust gases it is a major factor in acid rain. It is readily combines with water to form Nitric acid and as such attacks mucous membranes in the nose and throat.

We can provide a range of nitrogen dioxide detector solutions to meet your site requirements. From our addressable safe area gas detectors for car parks and engine testing areas, to our 750X series ATEX/IECEx explosion proof detectors for thermal power stations. No project is too large or too small. with over 100 years of industry leading experience and cost effective equipment, we are the go to choice for nitrogen dioxide detector solutions. We can also provide full project support to help support your team. Get in touch today to learn more.

Sources of NO2:

  • vehicle exhausts
  • Thermal power stations
  • pulp mills
  • butane heaters
  • gas stoves.

NO2 is also produced in industry being used as an inhibitor to prevent polymerisation of acrylates during distillation; as a nitrating agent for organic compounds; as an oxidising agent; as a rocket fuel; as a flour bleaching agent and in increasing the wet strength of paper.
