Air monitoring equipments for outdoor & indoor air quality - Air and Climate - Indoor Air

Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.

  • Traffic pollution
    • Spatial assessments, roadside or urban background locations.
    • Co-location with auto-analysers.
    • Nitrogen dioxide, Sulphur dioxide, Benzene, BTEX and Volatile Organic Compound (VOC) emissions, including Petroleum Hydrocarbons, TPH, PAH, Landfill Suites.
  • Landfill gas emissions
    • Air quality monitoring or soil gas sampling to identify the distribution of hazardous pollutants or odours.
    • VOCs, Mercaptans, Formaldehyde and Hydrogen sulphide.
  • Agricultural emissions
    • Farming practices can result in rural pollution including Nitrous oxide, Ammonia, and Pesticides.
  • Industrial emissions
    • Stack sampling and boundary emissions monitoring.
    • Sampling of a wide range of VOC and inorganic pollutant emissions.
  • Building on reclaimed land (brownfield sites)
    • Prior to construction - highlight areas of high concentrations of air toxics and assess the effectiveness of remedial actions.
    • VOC detection.
  • Environmental management
    • Assess the impacts of air pollution on forests.
    • Monitor emissions from natural phenomena such as volcanoes

  • Industrial emissions
    • Emissions from chemical, cleaning, industrial and manufacturing processes.
  • Building on reclaimed land
    • Migration of pollutants into the building due to insufficient remedial action.
  • Personal and workplace monitoring
    • Anaesthetic gases, VOCs, chemicals associated with specific work environment.
  • Paints, Furnishings and Floor coverings
    • Hazardous air pollutants often arise in indoor environments due to new products or from re-decorating.
    • VOCs and Formaldehyde.
    • BREAAM suite of tests for new buildings
  • Combustion - Heating systems and Smoking
    • Emissions of Nitrogen dioxide and VOCs can be monitored.
    • Particulate counts are especially important for people with respiratory health problems.
  • Cleaning chemicals
    • Residue from dry cleaning processes.
    • Sterilisation chemicals.
    • Paint stripper.
  • Drains
    • Odours can arise due to Sulphur dioxide, Acid gases and Ammonia pollutants.
  • Museums and libraries
    • Hazardous gases may damage valuable artefacts.
    • VOCs (including Acetic Acid), Ozone, Sulphur dioxide, Ammonia, Hydrogen sulphide, Formaldehyde and Nitrogen dioxide.
  • Migration of pollution from attached garages into homes
    • Vehicle emissions, fumes from stored paint, fuel, solvents, etc.
    • VOC monitoring, Nitrogen dioxide, Particulates.
