Nitrogen Dioxide Rapid Air Monitor

Gradko’s new range of Rapid Air Monitors (RAMs) brings together the ease of passive sampling with the added advantage of very short monitoring periods.

With sampling times from as little as 1 hour (for predicted high concentration areas only), the Nitrogen dioxide Rapid Air Monitor solves the requirement for fast results for inorganic compounds, previously only suitable for long-term monitoring with diffusion tubes. The rapid sampling times allow you to identify hazardous air pollutants even if you only have limited site access.

Currently available for Nitrogen Dioxide, Ammonia and Sulphur Dioxide sampling.

Need longer monitoring periods? Try our diffusion tubes for sampling periods of 2-4 weeks.

Sources of Nitrogen dioxide:

  • Vehicles.
  • Power stations.
  • Fuel or biomass burning, including controlled burning.
  • Natural processes.

Potential implications of Nitrogen dioxide pollution:

  • Health effects including respiratory irritation and aggravation of heart disease symptoms.
  • Ground-level Ozone formation.

Due to its health and environmental effects, Nitrogen dioxide is widely monitored. The Rapid Air Monitor allows you to quickly identify the levels of pollution so remedial actions can be implemented. 

Rapid Air Monitors can be used for outdoor ambient air monitoring, indoor air sampling and personal exposure monitoring.

  • External ambient air monitoring, for example at roadside or urban background locations.
  • Indoor air monitoring in roadside buildings, offices and in-vehicle concentrations.
  • Industrial monitoring.
  • Personal exposure or workplace monitoring for occupational health surveys and risk assessments (e.g. taxi drivers, bus drivers, machinery operators).
  • Environmental surveys – e.g. forest management.
